Abstract

Our model of the optical anisotropy shows clearly that the reorientation of the optical anisotropy cannot consist of collective rotation of atomic or molecular units as is the case in liquid crystal, for example. The rather unusual logarithmic time dependence of the orientation and reorientation processes can be explained by the plausible assumption that the heights of the barriers hindering the atomic displacements have an energy distribution whose spread is much larger than kT.
