Electric polarization of Onsager fluids

The problem of correct determination of electrical and optical characteristics of molecules of dielectric fluids can actually be brought to problem of description of the effective internal field which consist of the field included by external sources and the cumulate electric field of molecules on the medium including intermolecular interactions. An attempt was made to modify the model Onsager theory. A polarizable molecular dipole enclosed in spherical cavity is substituted for a rigid one submerged in polarizable medium which fills the cavity. The local dielectric permittivity of the Heaviside type is replaced for the oscillating, rapidly damping function of Fresnel integral. The analytic…
