Abstract
We discuss the problem of roto-translational diffusion of a rigid biaxial m olecule dissolved in a uniaxial smectic liquid crystal phase. We examine di storted rod and disklike molecules and show how biaxiality and roto-transla tional coupling can produce significant effects on some of the correlation functions and spectral densities most useful in analyzing experimental obse rvables.
