From: franklinhu on 11 Jul 2010 10:14 This article describes how to use simple Rydberg-like formulas to accurately calculate both the spectral lines and line intensities. The calculation of the spectra for atoms other than hydrogen or hydrogen like ions has long been considered to be complex multi-body problem which can only be solved with the use of supercomputers. Calculating the line intensities does not appear to be addressed at all in the existing literature. However, if you create a simple graph of the line frequencies and intensities for Helium, a striking and predictable pattern appears which suggests that the spectra and the intensity can be calculated using simple formulas based on the Rydberg formula. This pattern also appears in lithium and beryllium. The list of spectral data can be found at: http://physics.nist.gov/PhysRefData/ASD/lines_form.html A description of the Rydberg forumula can be found at: http://en.wikipedia.org/wiki/Rydberg_formula The Rydberg formula can be used to calculate the atomic spectra of Hydrogen and it can be extended to calculate the spectra of Hydrogen- like ions by adding a factor of Z^2. These ions are any atoms which have been fully ionized and a single electron interacts with only the positively charged nucleus. For example, if you remove the 2 electrons from Helium, this ion is identified as He II. If you only remove 1 electron, this is called He I. The spectra for He II can be calculated using only the extended Rydberg formula. If you plot the calculated He II spectra wavelength against the electron level transitions (e.g. 1->2, 1->3, ... 2->3, 2->4..etc.) on a logarithmic scale, the graph appears like a staircase leading up. When the starting energy level increase by 1 (e.g 1->2 vs. 2->3), this causes a large step up in the frequency. The calculated spectra matches up well with the observed He II spectra. Using the data from the NIST database and plotting spectral lines for He II against the observed values for He I, the plot for He I also appears as this same staircase pattern, but at a longer wavelength. This nearly identical shape suggests that the He I spectra can be calculated as simply being a scaled version of the He II spectra. The graph of He II (shown in pink) and He I (shown in yellow) spectra values can be found at: http://franklinhu.com/spectrahe.jpg The Excel spreadsheet used to create this graph and a Microsoft word document of this article is avaliable upon request. The NIST data contains the electronic transitions and the ions that represent the observed wavelength. In most cases, this is what was used to plot the point on the graph. The Y axis shows the wavelength in nanometers. The X axis lists the 32 electron transitions in ascending order. Since the He I spectrum appears so close to the He II spectrum, is there a simple formula that can transform one into the other? This is basically a curve fitting exercise. It does appear that a different formula can be applied at each energy level to calculate the spectral wavelengths. For N1 = 1 (transitions starting at N1 = 1), the curve can be represented by the formula: Rydberg(N1,N2)+28.14-(N2)*0.044 Where Rydberg(N1,N2) represents the result of the extended Rydberg formula for He II and N1 represents the starting electron level and N2 represents the ending electron level. For example, the 1->2 transition calculates to 58.427 nm and matches with the observed result of 58.43 nm. This appears to be a constant minus a scaling factor based on N2. For N1 = 2, the formula changes to: Rydberg(1,N2)*13-N2*3.55 This appears to be a scaling factor on the Rydberg formula minus a scaling factor of N2, howevever, the shape of the curve better matches N1=1, so the Rydberg formula is shown with a starting level N1=1. For n = 3,4,5,6 the formula is: Rydberg(N1,N2)*4 This is a straight scaling by 4 for all of the higher energy level shells. The following is the calculated He I spectral data. Columns N1 & N2 represent the electron shell transition number. The third column represents the observed wavelength and fourth represents the calculated wavelength. The last column shows the difference between the observed and calculated values which is typically less than a percent difference. On the graph, you will see observed wavelengths plotted in blue behind the yellow calculated values. The values are so close, that you can barely see the differences between the two.

This limited calculation provides at most 32 values and for He I, there are no observed values for transitions starting from the 5 & 6 level, so this calculation accounts for 27 or 96 lines. There may certainly be other processes involved which create the other observed values, however, it is remarkable how closely the observed values can be matched with the calculated ones. Another aspect of atomic spectra which appears to be absent in the literature is the calculation of the relative intensity for the spectral lines. If you do a similar plot of energy level transitions against the relative intensity found in the NIST data for hydrogen, this produces a very regular saw tooth shape. This is shown in the following graph for Hydrogen in pink. http://franklinhu.com/spectrah.jpg The relative intensity can be calculated for N1=1,2,3 as: (1/N1^3*1000)*1/(N2-N1)^(2.23-(N1^2)*0.13) For N1 = 4,5,6 (1/N1^3*1000)*1/(N2-N1) The intensity appears to drop as the inverse cube. These calculations are able to reproduce the observed relative intensities as found in the NIST data. The Hydrogen graph shows the calculated values in yellow and the observed values in pink. This exact same formula also appears to apply to the relative intensity for He II. The graph for Helium shows the experimentally observed values in light blue and the calculated values in purple for He II. For He I, the intensity follows the formula for N1=1, it partially follows when N1=2, but after that the relative intensity becomes chaotic and does not appear to follow any pattern. The same spectra analysis can be applied to the next element in the periodic table which is lithium. The graph of the lithium spectra can be found at: http://franklinhu.com/spectrali.jpg The calculated extended Rydberg formula spectra for Li III is shown in blue. For lithium II and I, the electron transition states stated in the NIST data do not directly provide all of the transition states required to plot the points on this graph. In this case, some of the points have been selected based upon where one would "predict" where a point would exist on the graph and using those points having the greatest relative intensity. The regularity of the pattern allows you to make these predictions. If you take a ruler and match up with any 2 of the peaks of the steps, you can predict where the next step should appear. After this peak, one would expect to find a set of 1/N2^2 decreasing values and relative intensities. By using this methodology, the experimental data has been matched to the electron transitions as shown in pink in the graph. The Li II values (shown as yellow in the graph) can be calculated with the following formulas: For N1=1 Rydberg(N1,N2)+6.42 For N1=2 Rydberg(N1,N2)*2 For N1=3,4,6 Rydberg(N1,N2)*2.3 For N1=5 Rydberg(N1,N2)*2.145+(N2-5)*124 Spectral data points can also be found for Li I which has 3 electrons bound to the atom with only 1 free electron. This also shows the familiar staircase pattern. The formulas for Li I have not been calculated, but it should be obvious that a best fit formula could be found for these data points. The calculations match fairly closely with the observed Li data except for N1=1 and N2=5-9. Here we see an unusual dip in the wavelength compared to calculations. This dip can also be seen in the Li I data as well, so there may be somethIng structural in Li that causes this deviation. The analysis for the next element Beryllium becomes even more difficult as we are faced with a nearly continuous spectra. For example, to do the analysis of Be I, the only points that appeared to be known with any confidence are the very highest transitions which have very few spectral lines in the longest wavelengths. Based on the slope of those data points, the rest of the points were selected. For Be, even the ion identification needed to be occasionally ignored to find best fit data points. Due to this difficulty, the exact quality of the data point selection is questionable. However, there is enough data to speculate that the overall shape and slope of the graph is correct and the graph contains most of the brightest observed lines. The graph of Beryllium can be found at: http://franklinhu.com/spectrabe.jpg Compared with lithium, we see that the Li III and Li II are closely spaced like Be IV and Be III. The next ion Li I and Be II appear to be further spaced away. Be I appears closely spaced with Be II. This similar pattern suggests that the ions may follow a predictable energy pattern and it provides confidence that the Be graph correctly describes the energy pattern. Conclusion: From the spectral data for hydrogen through beryllium, a regular pattern can be seen in the data. The spectra may initially appear to be a random collection of oddly spaced lines, but when you look at the pattern of overlapping wavelengths created by the different ions, it is easy to see how such a pattern is created. A relatively crude curve matching formula was created to match this pattern which was based only upon the starting and ending electron level N1 & N2. It is possible that more sophisticated analysis will reveal an even simpler formula to describe the very regular staircase pattern found in the data. Since the spectra can be described entirely as a function of N1 & N2, it would appear that the problem of calculating spectra may not be a complex multi-body problem as was previously thought. Whatever effect that the electrons have in shielding the nucleus, this effect appears to be constant and so you only need to consider the nucleus and the electron as a simple two body problem like it is in the original Rydberg formula. However, not all of the spectra can be explained, as there are still numerous unexplained lines. However, by eliminating the points which can be explained, it may be possible to find further patterns in the unexplained lines. These other lines may require complex multi-body calculations. These calculations also do not take into account any fine differences such as the lamb shift. It only covers transitions that can be described using N1 and N2 as parameters. Only the first four elements have been examined using this analysis. This can be extended to the other elements as well and other regularities may appear which may further enhance our understanding of the atom. The formulas derived could also have other uses such as in the generation of synthetic spectra for use in astronomy and may lead to a more accurate understanding of which lines belong to what electronic transition. These formulas may allow the prediction and detection of as of yet undiscovered spectral lines. It is extremely surprising that the regularity of the spectral lines has not been prominently noted in the literature. The analysis done here is extremely simple and obvious. The regularity of the H and He II relative spectral intensity should be part of any standard description of the spectra for H and He as it follows a very regular pattern. The formulas presented may have been created Ad Hoc to match the data and it is unclear why they have the form that they do. However, like Bohr and Rydberg who were also unable to explain why the spectra appear the way they do, it is important to continue to explore and find patterns within the data that can be described by simple formulas in the hopes that one will find the underlying mechanisms. This analysis deserves further research and may open new avenues in the science of the atom. fhuspectra
From: franklinhu on 13 Jul 2010 01:42 I see that no one has posted any reply to this article. According to the unwritten law of usenet groups, if you can't say anything critical, don't say anything at all and so the highest praise is to get no response at all. So come on PD, Tom, Sam, Eric - you must have read this post and had something to say about it. Your lack of response tells me that there isn't anything obviously wrong with what I have proposed. The ability to describe a large part the spectra for helium and beyond using the Rydberg formula must be significant find. This should be as big a find as the orginal Rydberg formula itself and goes well beyond what can be easily calculated using quantum mechanical theory. Whenever this question has been asked in sci.physics, the answer always comes back that the spectra for non-hydrogen like ions is difficult to calculate and the line intensity cannot be calculated except through complex probability analysis. What I still find hard to believe is that nobody else found it before me. The analysis I performed was truly trivial and the pattern that emerged was blatantly obvious. Please tell me that ALL of the real scientists really didn't miss this most obvious of patterns? If everyone missed this pattern, then I would say that science is truly in a sad, sad state if it takes a crackpot amateur mad scientist like myself to notice and post these results. If this pattern was noticed before, then why isn't it listed beside the description of the Rydberg formula as a further extension? I wanted to stick with the facts about how the spectra could be calculated, so I did not incorporate what it means in terms of the atomic model. But here is the bottom line. Because the spectra of the ions can be calculated by only knowing N1 & N2, this means that the electrons which are still in the atom, have NO variable shielding effect and must be incorporated into the nucleus itself. This means no S, P, D, etc. shells extending outside of the nucleus at some large distance relative to the size of the nucleus. When an electron is not ionized and is part of the atom, it cannot be distinguished from the charge center of the nucleus. It simply reduces the positive charge of the nucleus and has no physical extent beyond the nucleus. This is why the spectra can be calculated knowing only the starting and ending energy states. It is strictly a two body problem. There is no three body problem of the positive nucleus, non- ionized shielding electrons and the electron undergoing the transition. If you have been following along with my cubic atomic model, this is exactly what it predicts. The electrons are incorporated into the nucleus in an alternating checkerboard pattern and the nucleus is much larger than we currently think it is. When an atom is ionized, an electron leaves the atom, but it leaves the rest of the electrons behind bound into the solid atomic nucleus matrix. They do not in any fashion "orbit" or "cloud" around the positively charged nucleus. If they did, then I would think that we would see more of a continuous spectra for most atoms since such variable "orbits" would allow nearly unlimited energy states. I believe that cubic atomic model is well supported by the evidence that the spectral calculations are not a multi-body problem. I would challenge anyone who believes otherwise to explain why it is that the spectra can be calculated as a simple 2 body problem? So there you have it, I have found the pattern and formula that allows you to trivially calculate the complete spectra of atoms as a function of only 2 variables. Apparently, nobody has been able to do that before. That should be a pretty big deal - isn't it? Now I know it isn't at all fashionable to support or collaborate on anything found on the usenet - it isn't any fun if you can't tear somebody apart. But really, this could be quite sigificant and I would like to get your ideas and input on this. For further information on my cubic atomic model, see: http://franklinhu.com/atmpics2.html This is part of my larger theory of everything. http://franklinhu.com/theory.html

There are no simple solutions to "how" or "why" or "what" in this world, even though there are legions of internet cooks trying to convince us they have found them in an afternoon of contemplation, or after a lifelong introspection. Those methods will never explain anything. That however wont stop them dreaming. Well, I have to increase the use of the kill button and killfile.

Surely, you would have found something to say about how this supports my cubic atomic model - you couldn't possibly let that stand. I would have expected comments about how this has been noticed before, or how the analysis was done incorrectly, or I just made the whole thing up or I cherry picked the points, or something. I spent a fair amount of time doing this analysis and making sure it was air tight. There is little to argue about a formula that reproduces the experimental results. I think this is a pretty good piece of basic scientific research. Why do you ignore it???? |
