Abstract

We introduce a continuum model of dielectric friction on an ion in a polar liquid. This model couples hydrodynamic motions of the polarized solvent to dielectric relaxation by both rotational diffusion and translational diffusion of solvent molecules. We show that in solvents with sufficiently long dielectric relaxation times, translational diffusion is the dominant relaxation mechanism. We compare our predictions with experimental data on ion mobilities in nematic liquid crystals.
