The dependence of the third-order nonlinear susceptibility, χ(3), of CS2 and C18H30 (dodecylbenzene) on temperature was measured by the method of degenerate four-wave mixing. The empirical formula for this dependence was obtained. An explanation of this relationship was also given through the application of the model of a polar molecule moving in a viscous medium under the action of a laser beam.
