Molecular Anisotropy, Mutual Orientation of Molecules of Liquids, and Light-Scattering of Liquid-Mixtures
The anisotropic component of light scattered by liquids carries information about the anisotropy of the polarizability tenser of the molecules in the liquid and about the mutual orientation of the neighboring molecules. These two pieces of information cannot be separated when the scattering measurements are performed on pure liquids. A computational procedure is developed that can separate the two effects when the anisotropic scattering is measured as a function of the composition of a two-component liquid. The procedure was tested on the benzene-cyclohexane system. It was found that benzene molecules in pure benzene are preferentially oriented perpendicularly to each other.
