dc.description.abstract	Infrared reflectivity spectra of CuInSe2, CuGaSe2 and CuIn1−xGaxSe2 solid solutions have been investigated for the polarizations E\|c and E⊥c. Reflectivity spectrum contours are calculated and phonon parameters and dielectric constant are determined. The dependence of the longitudinal-transverse splitting, the oscillator strength and the damping factor on x composition are shown. Raman scattering of CuIn1−xGaxSe2 solid solution has been investigated. Effective ionic charges for ions of these materials are determined. Two-phonon absorption spectra in CuGaSe2 and CuInSe2 have been investigated and absorption bands have been identified in accordance with selection rules.	en_US
