Opis:: The Kerr constants of pure liquid organic compounds, which exhibit weak intermolecular interactions and possess widely varying electric, optical and polarizational molecular parameters, were computed from the data on dielectrometry and electric birefringence. Good agreement of the calculated and observed values was reached as the result of the introduction of the local field model, which develops the concepts of reactive field and local electric induction of a polarized fluid, into the orientational theory of the Kerr effect.

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

Opis:: 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.

Opis:: On the ground of dielectrometry and electric birefringence data we calculated molar Kerr constants of substances dissolved in organic media of diverse polarity and polarizability under the conditions of infinite dilution. Minimal errors of the calculated constants, in relation to their gaseous phase values, were achieved as a result of the introduction of the local field model, which evolves the concepts of reactive field and local electric induction of a polarized fluid, into the orientational theory of Kerr effect.

Opis:: A comparative analysis of several methods of interpretation of solvent influence on molar Kerr constants of solutes was done. The analysis was based on experimentally determined electro-optical and dielectric properties of binary solutions of organic substances with various polarities, polarizabilities and optical anisotropies. It was found that the role of universal van-der-Waals interactions treated via London-Debye-Keesom potentials was best accounted for by a modified orientational theory of Kerr effect that developed the ansatz of reactive field and local dielectric permittivity. An extrapolation method of determination of gas phase molar Kerr constants of solutes was deduced from the theory.

Opis:: A comparative study of the methods of interpretation of solvent influences on electric properties of molecules was conducted based on experimental dielectric properties of dilute solutions of organic substances of various polarity. It was shown that the solvent effect estimated via London-Debye-Keesom pairwise interaction potentials is best accounted for by theories of polarization of condense media which develop the anzatzes of reactive field and local dielectric permittivity.
