ELECTRIC POLARIZATION OF ONSAGER FLUIDS .1. DIPOLE POLARIZATION .1. ELECTRIC MOMENTS OF FREE MOLECULES

An attempt was made to modify the model Onsager theory. A polarizable molecular dipole enclosed in a spherical cavity is substituted for a r igid one submerged in the polarizable medium which fills the cavity. T he local dielectric permittivity of the Heaviside type is replaced for the oscillating, rapidly damping function Of the Fresnel integral. Th e analytical expressions deduced allow to estimate dipoles of free mol ecules, starting from the results of dielectrometry of polar fluids. T he obtained values are as close as possible to the experimental data o n a great variety of pure organic liquids.
