Mixtures of cholesteryl benzoate and p-azoxyanisole present a cholesteric phase. Measurements were made, by optical methods, of the rotatory power and pitch of mixtures containing 5, 10, 15, 20% of benzoate in p-azoxyanisole. Mauguin's theory, as extended by de Vries, expresses rotatory power as a function of pitch and double refraction of the thin anisotropic helically stacked layers. The results permit verification of the Mauguin–de Vries theory and, if we compare them with Cano's results for other mixtures, the Maier–Saupe theory.
