TL;DR: In this paper, the electro optical Kerr coefficients of binary liquid mixtures, comprising of aprotic-aprotic molecules only, are measured over the temperature range of 286 K to 315 K.
Abstract: The electro optical Kerr coefficients of binary liquid mixtures, comprising of aprotic-aprotic molecules only, are measured over the temperature range of 286 K to 315 K. To with in experimental errors, the logarithm of Kerr coefficient can be expressed as Van't Hoff type expression to the reciprocal of temperature. Information on the interaction energy between the constituents of the binary mixtures is thereby obtained. It is found that the interaction energy in aromatic ketone-aliphatic nitrile binary mixtures is comparatively higher than in the binary mixtures with aliphatic ketone-aliphatic nitriles, aromatic ketone-aromatic nitrile and aromatic ketone-aliphatic ketones components. This is attributed to the dipole-dipole interaction existing between the components of the binary mixtures.

TL;DR: In this article, molecular refractivity and polarizability of a particle is defined as the dipole moment induced by an electric field of unit intensity, and the principal polarizabilities of molecules can be analyzed in terms of anisotropic bond polarisation.
Abstract: Publisher Summary This chapter discusses molecular refractivity and polarizability. Refractive indices ( n ) of pure substances are more accurately measurable than any other optical properties. The refractive index of a substance varies with its physical state, temperature t , and wave-length λ of the light by which n is observed. The first two of these effects are attributed to the density d . The specific refraction r of a substance multiplied by the molecular weight is referred as molecular refraction. Polarizability of a particle is defined as the dipole moment induced by an electric field of unit intensity. The polarizabilities of monatomic ions and molecules are generally independent of field direction. The principal polarizabilities of molecules can be analyzed in terms of anisotropic bond polarizabilities. Polarizabilities are also responsible for the birefringence, which appears whenever the orientations of anisotropic molecules in an assemblage are derandomized or changed by any disturbing force.

TL;DR: The electric dipole moment induced in a helium atom by a uniform electric field F can be expressed by αF+⅙γF3+···, where α is the well-known electric polarizability, and γ is a higher polarizer describing the initial deviation from a linear polarization law, and is sometimes called the hyperpolarizability as discussed by the authors.
Abstract: The electric dipole moment induced in a helium atom by a uniform electric field F can be expressed by αF+⅙γF3+···, where α is the well‐known electric polarizability, and γ is a higher polarizability describing the initial deviation from a linear polarization law, and is sometimes called the hyperpolarizability. An experimental determination of γ has been made by observation of the Kerr electro‐optical effect in helium. The result is γ = (2.6±0.4) × 10−38 esu. An analytic calculation has been carried out by a perturbation procedure, with the results γ = 1.57×10−38 esu, α = 0.2027 A3. The observed value of α is 0.2051 A3. Approximate calculations of the quadrupole moment of helium induced by an electric field and a field gradient are also described.
