Abstract
Far-infrared reflectivity and Raman scattering have been studied in Cd xZn1-xSb (x = 0, 0.12, 0.92, 1) single crystals at 300 K. The composit ion dependence of 12 IR active phonons (out of 15 predicted by symmetr y) and 16 Raman active phonons (out of 24) has been surveyed. This dep endence corresponds generally to 'one-mode' behaviour, with the exclus ion of extra high-frequency peaks at x = 0.92 that may be ascribed to 'two-mode' type. For CdSb, some new phonon peaks are found. For ZnSb, the new data confirm the results obtained recently by the magnetophono n resonance method.
