Abstract

The total light scattering coefficient, degree of depolarization, refractive index, and density were measured in chlorobenzene–o-dichlorobenzene solutions. The isotropic and anisotropic molecular light scattering intensities, isothermal compressibility, excess isothermal compressibility, molar volume, and excess molar volume were calculated. Complex nonmonotonic behavior of light scattering coefficients in response to the concentration change was found. A minimum of light scattering intensity in low concentration range at the chlorobenzene side and the maximum of light scattering intensity at the o-dichlorobenzene side were observed, which indicates a substantial rearrangement of solution local structure with a change in the concentration. Four ranges with different local structure of the solution were distinguished, namely, 0–0.03; 0.03–0.65; 0.65–0.9; and 0.9–1.0 according to analysis of light scattering coefficients, excess isothermal compressibility, and excess molar volume. The solution local structure was described in each range.
