Diffusion equations are used to describe rotational, translational and internal motions of molecules in uniaxial liquid crystal phases. In addition to exact numerical solutions based on eigenfunction expansions, approximate procedures are also presented to gain direct insight into the relevant aspects of the dynamical problems. Inherent limitations, intrinsic time scale separations and improvements of the model are discussed.

Abstract
Diffusion equations are used to describe rotational, translational and internal motions of molecules in uniaxial liquid crystal phases. In addition to exact numerical solutions based on eigenfunction expansions, approximate procedures are also presented to gain direct insight into the relevant aspects of the dynamical problems. Inherent limitations, intrinsic time scale separations and improvements of the model are discussed.
