I am a user of both Mathematica ver 4 and 7 On ver 4, "PrincipalValue->True" is recognized and works fine for "FourierTransform". But on ver 7, this seems to be no longer recognized (But it looks doing something compared to evaluation without "PrincipalValue->True", though not satisfactory) For the purpose to get simply a Plot (Complex), I know using "NFourierTransform" is easier and faster But I need to apply further calculation to the product I get by "FourierTransform" Expression I want to apply "FourierTransform" is following ;

Exp[-(x^2)/2 +I*(1-Sin[3*x])/2]

It looks Sin[3*x] makes Evaluation a little complex Is there any substitute Option available on ver 7 in place of "PrincipalValue->True" ? Your advise will be highly appreciated
