Abstract

A multidimensional Fokker-Planck-Kramers equation for rotational relaxation of small solutes in complex liquids is developed wherein collective solvent effects are explicitly represented by rotating torques and stochastic fields. A simplified version of the model is applied to interpret the breakdown of the Hubbard-Einstein relation at high viscosities.
