Abstract
The damped diffusion model presented in the previous paper is applied to the 'H NMR relaxation rates and dielectric loss data of poly(viny1 acetate) in toluene. The results are compared to those obtained from the cutoff diffusion model of Bendler and Yaris and the model of Valeur, Jarry, GBny, and Monerie applied to the same system. The damped and cutoff diffusion models give identical fits to experiment. The model of Valeur et al. also fits the experimental results but only at the expense of nonphysical values for the parameters. A tentative interpretation of the physical origin of the molecular motion is presented.
