Local field in liquid dielectrics: A two-parameter mean field approach

Abstract: In the molecular field approximation, one derives an expression of the static dielectric constant of an isotropic liquid involving renormalized expressions of the molecular dipole and polarizability. The long-range moderate attractive forces are treated as a perturbation of the short-range intense repulsions, so that two parameters λ and η describe the short-range correlations and the long-range order, respectively. On the condition of a superposition hypothesis, the model is compared in its hard-sphere limit (λ=0, η=1) with the available experimental data about a series of organic liquids and with Onsager's continuum approach.
