Abstract
Polarized absorption and wavelength modulation spectra of a complete series of single crystals near the excitonic bands have been studied in the temperature range 80-300 K. The large dichroism of absorption was observed, which depends on the composition of the crystals and the wavelength of the radiation. A qualitative explanation is given for the observed optical absorption critical points of the layered crystals.
