Investigation of polarization in the smectic liquid crystals by the methods of statistical physics. Usually in the theoretical works the value of spontaneous polarization is examined within the framework phenomenological theory, but the molecular aspects of the appearance of spontaneous polarization usually are not considered. In some publications, the appearance of spontaneous polarization was described at the molecular level, but the distribution of molecular dipoles was obtained as a result of expansion of polarization in Taylor series, and thus, the role of molecular theory was reduced to the determination of coefficients in the phenomenological theory. At the same time, for the simplest tilted smectic phases, synclinic and anticlinic, it is possible to find the distribution of molecular dipoles by the method, analogous to Mayer- Saupe theory. In our study, the origin of the spontaneous polarization in the synclinic and anticlinic smectic liquid crystals is obtained within the framework of molecular- statistical theory. The influence of interaction of molecules, external electric field and molecular bent on the value of polarization is studied.
