Abstract Temperature and composition dependence of the pitch in cholestryl chloride and cholesteryl nonanoate mixtures have been obtained by means of the selective reflection-total reflection method, the Bragg-like reflection method and the optical rotatory power method. The results are analyzed using the generalized long range distortion theory. The temperature variations of the molar twisting power between component molecules of the mixture have been determined.
