摘要：

A model of brownian motion in a fluid or disordered solid is developed whereby cooperative motions are accounted for in the shell of nearest neighbours of a given molecule. This is mathematically tractable for the angular fluctuations in a plane of a dipole vector embedded in the asymmetric top. The Fokker-Planck-Kramers equations of motion are developed from the initial stochastic differential equations and full solutions derived in terms of multivariate probability density functions. An integro-differential representation of the same system is solved in terms of a generalized Fokker-Planck equation derived by Davies and Evans [24] and valid for a column vector of n linearly independent dynamical variables. © 1979 Taylor & Francis Group, LLC.
