Abstract

Benoit's theory of the time dependence of the birefringence transient in the Kerr cell following sudden removal of the orienting field has been examined and shown to hold only for spherical part ides and not ellipsoids of revolution. This observation is in agreement with the methods of dielectric dispersion and depolarization of fluorescence which yield two rotary diffusion constants, while Benoit's theory yields only one. A new theory is presented here which contains two rotary diffusion constants and reduces to the Benoit equation in the limiting cases of spheres and infinitely thin rods. Also the theoretical extensions of Tinoco and Ridgeway have been examined and compared to the resulting theory.
