Extraction of T-2 from NMR linewidths in simple spin systems by use of reference deconvolution

We investigated the possibility of obtaining transverse relaxation times th rough linewidth measurements in NMR spectra of simple spin systems (subsyst ems). The spectra are subjected to reference deconvolution and subsequently to time domain data analysis. The time for the experiment is usually short , stringent instrumental stability should be maintained during the experime nt. The approach described here produces correct results if the lineshape i s Lorentzian. Rough width estimation is achievable in other cases. As an ad ditional result, detection of very small couplings is possible. Copyright ( C) 2001 John Wiley & Sons, Ltd.
