Statistical Theory of Dielectric Fluids

Abstract

A formal cluster expansion theory of the dielectric constants and the susceptibilities of nonpolar fluids is developed and the deviation of the Clausius-Mossotti equation from experiments is discussed. Many-body polarization effects are considered in terms of diagrams. A chain-diagram approximation gives the susceptibilities in terms of the Fourier transforms of the Mayer f function and of the effective dipole interaction tensor.
