【Abstract】 The correlation functions of side-groups of polymers were given for NMR relaxation if the polymer chains undergo scgmental motion, these functions were de-nved from nonequivalent two sites and three sites jump internal rotations, stochastic diffusion internal rotation and restricted internal rotation. The corresponding spectra! density functions were also given, and two examples were discussed.更多还原
