Based on the Maier-Meier theory, a model is proposed in which the electric permittivity values of the cholesteric liquid crystals can be linked to their molecular parameters (μ - dipole moment,α - polarizability). To accomplish this project there were defined the transformation principles from the liquid crystal structure frame to the molecular frame, and a method for rendering the single molecule parameters (μ, α) into a set of averaged quantities of the macroscopic ensemble was offered. This model was used to calculate a dipole moment and polarizability for two liquid crystalline materials from electric permittivity measurements. The results are compared with the data obtained from MP3 calculations.
