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

Abstract

A software package which allows the correct determination of individual relaxation times for all the nonequivalent nuclei in poorly resolved NMR spectra is described. The procedure used, based on the fitting of each spectrum in the series recorded in the relaxation experiment, should improve the analysis of relaxation data in terms of quantitative dynamic information, especially in anisotropic phases. Tests on simulated data and experimental examples concerning 1H and 13C T1 measurement in a solid copolymer and 2H T1Z and T1Q measurement in a liquid crystal are shown and discussed
