The Method of the Order Parameter “S” Calculations for Cholesteric Liquid Crystals

Abstract On the basis of experimentally determined polarisability anisotropy the order parameter S for cholesteryl propionate, nonanoate and decanoate was calculated. In this work to avoid difficulties in the determination of S for other esters of the investigated homologous series a method of calculation S is proposed. The So and η coefficients were obtained from the equation It makes the calculation of the temperature dependence of S for any compound of the series of cholesteryl esters of homologous fatty acids possible. The method was verified for cholesteryl myristate.
