Optical spectra of molecular crystals with two molecules in their elementary
cell are investigated. Depending on the polarization angle one or two exciton
excitation bands can be realized in the spectrum. The bands are separated
by the terminal frequency interval. The exciton absorption bands genesis
and the peculiarities of the function of their form at the change of the
laser radiation polarization have been analyzed and the regularity of arising
bistable states in organic benzol-type crystals has been established.
