Yanxiang Wang, Deyan Shen. The Application of Relaxation of Solid State NMR in the Study of Polymer[J]. Polymer Bulletin, 1996,9(3):152-158. DOI: 10.14028/j.cnki.1003-3726.1996.03.004.
This paper reviews the application of relaxation of solid state NMR in the study of polymer. It discusses the relaxation process of magnetic nucleus and its relation with molecular structure and molecular motion in following five aspects: (1) the spin-lattice relaxation process
(2)The
13
C spin-lattice relaxation process in the rotating frame
(3)The rate of cross polarization and the
1
H spin-lattice relaxation process in the rotating frame
(4)The spin-spin relaxation process
(5) The relation of line shape and molecular motion.
