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.
