Electric Polarization of Onsager Fluids. 1. Dipole Polarization. 2. Binary Solutions of Organic Compounds

Set forth in the previous report [1], the continual theory of dipole polarization of molecular fluids, which suggests substitution of the rigid Onsager sphere for the polarizable body and takes into consideration electric induction of this body and its nearest surroundings, is extended in this paper to binary solutions with diverse polarities. Dipole moments of free molecules of dissolved substances were calculated from experimental data of dielectrometry of a large number of extremely diluted organic substances and are close to the corresponding gaseous phase values. On the ground of solution polarization measurements the criterion of physical consistency of various models of the condensed medium internal field is proposed.
