Abstract

A simple and experimentally convenient method for determination of the twist elastic constants of the c-director in tilted smectic phases is proposed. The method consists in measurement of changes in electrical permittivity at high frequencies (about 1 MHz) caused by a dc electric field applied in the direction parallel to the smectic layers. The computer controlled apparatus performing the whole experiment has been described. The results of measurement of an effective elastic constant in a ferroelectric liquid crystal are presented.
