The Clausius-Mossotti relation for anisotropic molecular fluids

Abstract

It is shown that in the interior of a uniformly polarized homogeneous anisotropic fluid there exists a family of similar surfaces, determined by the two-particle correlation function, having the property that the dipole field at the origin due to molecules within these surfaces is zero. The resulting Clausius–Mossotti relation contains a parameter, ηαβ, which is a measure of the anisotropy of the molecular distribution. These results are applicable to nematic liquid crystals.
