Abstract

The molecule of liquid crystal can change its polarizability tensor components in two manners. First, the part of molecule rotates around the other one, and second the electron proton distance in molecule atoms decreases when the temperature of liquid crystal sample increases. The polarizability tensor components (alpha) _(parallel) or (alpha) _{(perpendicular}) include the both changes in their values. In this article we want to separate the both changes. It is possible because the first change is a linear function of temperature. In order to do it we must calculate the quantity (alpha) _{(perpendicular})/(alpha) _PLL which is a linear function of temperature. Knowing the inclination coefficients of these linear functions we have a possibility to calculate (alpha) _(parallel)-(alpha) _(parallel)`) or ((alpha) _PRP - (alpha) _{(perpendicular})`) in order to obtain the change of polarizability tensor components connected with rotational part of molecule conformation.
