✦ Synopsis

The Redfield formalism is used to describe nuclear spin relaxation in weakly coupled spin-pair systems for which differential relaxation is both expected and observed. The utility of longitudinal versus transverse relaxation studies is explored with respect to fully characterizing the molecular parameters related to spin relaxation. Account is taken of the fact that intermolecular spin interactions influence the overall spin relaxation process. When used in conjunction with data from coupled longitudinal relaxation experiments, transverse relaxation measurements provide information about low-frequency molecular motions. Experimental results of the systems 31 P 1 HO 2y and 31 P 19 FO 2y are given.
