Hello, I'm a NMR newbie working on Bruker 300MHz and my problem may sound silly to some of you, but I don't want to make mistake in the very beginning. I do the FT and phase correction of measured spectra in TopSpin, but after that I'd like to analyze manually (with other software) integrals and half-widths of deconvoluted lines. And here comes the question - which line one should I take into consideration: real part or magnitude? E.g. if I want to evaluate T2* from the halfwidth using the formula T2*=1/(piFWHM)?

1	If you prefer to work with ascii data in a csv format use convbin2asc to convert the spectrum into a txt file. link answered Jun 04 '14 at 19:40 Clemens Anklin 416

0	If I understand what you want to do, you would need to use the real part of the phase sensitive spectrum. For Bruker data this would be the "1r" file, which is most often 32 bit signed integer. link answered May 27 '14 at 09:56 Kirk Marat 711
