摘要/Abstract

摘要： 本文导出了聚合物为链段运动时,侧基进行非等价二位置和三位置跃迁内旋转、随机自由扩散内旋转以及受阻内旋转时的NMR弛豫相关函数,同时给出了相应的谱密度函数,并讨论了两个应用实例。

Abstract: The correlation functions of side-groups of polymers were given for NMR relaxation if the polymer chains undergo scgmental motion, these functions were demved from nonequivalent two sites and three sites jump internal rotations, stochastic diffusion internal rotation and restricted internal rotation. The corresponding spectral density functions were also given, and two examples were discussed.

Key words: Correlation functions, NMR relaxation, Side-groups of polymers
