Fuoss-KirkwOod distribution models of correlation times
the con-formational jump model proposed by Valeur et al. and the damped orientational diffusion model of polymer local main-chain motion proposed by Skolnick and Yaris were used to fit the experimental 13C-NMR spin-lattice relaxation times (T1) and nuclear Overhauser effect (NOE) data of 1
2-polybutadienes in CDCL3 solution. The dependences of the malecular motion of 1
2-PBD on the chain-structure ad temperature have been discussedin terms of the molel parame-ters obtained.
