Theory of Kerr Effect in Benzene C₆H₆(Anisotropic Molecule), Nitrobenzene C₆H₅NO₂ and Water H₂O (Polar Molecules)

Abstract

The Kerr constants in C₆H₆ and C₆H₅NO₂ are discussed by means of the statistical mechanics of Maxwell-Boltzmann’s distribution of the molecules under the biasing field. The anisotropic electronic polarizabilities are obtained as α₁=12.06 (ų) (parallel to C₆H₆ plane) and α₂=7.143 (ų) (perpendicular to C₆H₆ plane) for the Kerr constant 6.0×10⁻¹⁸ in C₆H₆, and also α₃=13.644 (ų) (parallel to the polar axis) and α₁+α₂=26.50 (ų) for the Kerr constant 269×10⁻⁷ in C₆H₅NO₂.
