title: Theory of the dielectric susceptibility of nonpolar biaxial liquid crystals.
abstract: A statistical theory of the dielectric susceptibility of nonpolar liquid crystals, whose constituent molecules are biaxial, is proposed. The ordering is described by means of the mean field theory, in which a set of basic functions is introduced. The dielectric susceptibilities are derived using a generalized Clausius-Mossotti approach. The theory was used to calculate the temperature and the density dependence of the order parameters and of the susceptibilities. On increasing the density, an ordering reversal of the corresponding susceptibilities is obtained.
