Microcanonical features of a liquid crystal molecule reflect on its macrocanonical properties. The critical temperature of the liquid crystal largely depends on its exact size and character of the substructure of a liquid crystal molecule. The series of liquid crystal molecules which have the same skeleton were investigated by the vibrational Raman spectroscopy. T'he changes of the polarizabilities of the each vibrational line are recorded as the function of temperature in the process of the phase transition. The function of the polarizability for the each vibrational line exhibits the characteristic change in the process of the phase transition. The lines which are due to the normal coordinate having the specific vector against the molecular axis show the irregular dependence on the increasing of temperature in the process of the phase transition.
