Gas Cotton-Mouton constant measurement by extrapolation in dissolved binary liquid solutions

The magneto-optic Cotton-Mouton effect constant C, light refraction index n and density ρ of binary solutions of toluene in carbon tetrachloride, α-picoline and β-picoline in 1,4-dioxane have been measured at different concentrations. The results have been used for the calculation of the molar CM constants of the solutions. By extrapolating the values CM = CM(f2) for the concentration f2 → 0, the constant ∞C2M = gasC2M of the dipolar component of the solution has been found, which is interpreted as the Cotton-Mouton gas constant. For all solutions, the reduction factors of the dissolved component have been calculated and their linear dependence on the solution concentration has been found.
