The SPORT-NMR software: A tool for determining relaxation times in unresolved NMR spectra

A software package which allows the correct determination of individual rel axation times for all the nonequivalent nuclei in poorly resolved NMR spect ra is described. The procedure used, based on the fitting of each spectrum in the series recorded in the relaxation experiment, should improve the ana lysis of relaxation data in terms of quantitative dynamic information, espe cially in anisotropic phases. Tests on simulated data and experimental exam ples concerning H-1 and C-13 T-1p measurement in a solid copolymer and H-2 T-1Z and T-1Q measurement in a liquid crystal are shown and discussed.
