摘要：

Reflectivity spectra of CdGa2Se4, CdGa2S4 and CdA1(2)S(4) crystals have been investigated in the range 1-6 eV for the polarization E parallel to c and E perpendicular to c at 300 and 77 K. The valence band splitting caused by spin-orbital interaction and by crystal field are calculated for the point k = 0. The band model has been built in actual points of the Brillouin zone Gamma, N, T, P.
