THEORY OF DIELECTRIC POLARIZATION IN NON-POLAR FLUIDS

Abstract

The dielectric constant of non-polar fluids does not agree with the Clausius-Mossotti formula. The deviation is calculated taking the induced dipole-dipole interactions into consideration. Since the induced dipole moments suggest that the molecules are most likely deformed, the theories developed by Kirkwood, Jvon and others are generalized to treat non-spherical molecules.A new mathematical method is introduced, and the dielectric constant is calculated as a function of the molecular anisotropy. In particular, the so-called rotational fluctuation is found to be composed of two terms, one representing the optical and the other corresponding to the geometrical anisotropy. (Author)
