Abstract
Up to now only the trace and the components (alpha) 1, (alpha) 2 of polarizability tensor of liquid crystal sample have been investigated. The new method of (alpha) (parallel) and (alpha) (perpendicular calculation of cholesteryl nonanoate molecule was described in this work. It was determined the (alpha) (parallel) and (alpha) (perpendicular) were nonlinear functions of the temperature. It proves that cholesteryl nonanoate molecule changes its conformation. Besides, the values are always constant in all mesophase temperatures and the value of ((alpha) 1-(alpha) 2)(Delta) n must be also independent on the temperature.
