Kerr constant-dispersion measurements on benzene and carbon tetrachloride

Abstract

The electric birefringences displayed by the above two liquids have been measured photometrically at wavelengths between 375 and 625 mμ, and Kerr constants Bλ computed relatively to benzene, for which B₅₈₉ is 0.410 x 10^-7 at 25º. Empirical equations connecting Bλ values and refractive indexes with X are developed, and compared in applicability with others from the literature. Data necessary for the determination of molar Kerr constants of coloured solutes in the named solvents are also recorded.
