Light-Scattering Study of the Critical Behavior of a Three-Component Liquid Mixture

Abstract
Light scattering measurements were made in the ternary system bromobenzene-water-acetone, with the acetone playing the role of an impurity. Because of the long range of the concentration fluctuations exhibited by this system, it was possible to explore with relative ease the nonhydrodynamic as well as the hydrodynamic regimes. Measurements of both the intensity and spectral width of the scattered light yielded a number of parameters which could be compared with several forms of theory.
