Reflectivity spectra of CdGa2Se4, CdGa2S4 and CdA12S4 crystals have been investigated in the range 1-6 eV for the polarization E It c and E Z 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 b
