Infrared reflectivity spectra of (Cu,GeSe,)l-, (CuGe,P,), mixed crystals with z = 0.1 and 0.2 are measured in t h e wave-number range from 180 t o 4000 cm-l. An analysis of the spectra reveals contributions from five vibrational modes and from free carriers t o the reflectivity. The results are comp
