<description xml:lang='en' descriptionType='Abstract'><p>Excitonic reflection spectra of CuAlS2 crystals were measured at a temperature of 10 K for E||c and E||c polarizations. The shapes of the lines of ground states of Г4 and Г5 excitons were calculated by means of the Kramers-Kronig relations. Exciton parameters and the values of energetic gaps (Г7-Г6, Г6-Г6, and Г7-Г6) were determined. Optical reflection spectra in the depth of absorption band (Еg - 6 eV) were measured at 80 K for E||c and E||c polarizations. Optical functions n, k, &epsilon;1, &epsilon;2, d2&epsilon;1/dE2 and d2&epsilon;2/dE2 were calculated for both polarizations. The revealed peculiarities are ascribed to electronic transitions in the frame of theoretical calculations of the band structure for crystals from this group.</p></description>
