• A Geometrical model is presented which rationalizes the viscosity and self-diffusion coefficients and their anisotrcpies in nematic liquid crystals. The model is an extension of Eyring's theory of the liquid state to the anisotropic fluid, based on the geometry of the constituent molecule. A novel concept, effective anisotropy factor of a molecule, is introduced which is determined from the viscosity coefficients. An empirical law on the principal viscosity coefficients by Kneppe <I>et al.</I> is given its molecular basis by this model. Self-diffusion coefficient tensor calculated from the available viscosity data of PAA, MBBA, and HBAB agree well with experiment.
