Abstract

Raman scattering in CuCl has been the subject of many studies which were in part motivated by its anomalous transverse optic (TO) region [1].** CuCl has the zincblende structure; the first-order Raman spectrum should show one TO phonon peak and one longitudinal optic (LO) phonon peak. A peak occurs at about 210 cm−1 which can be identified from polarization selection rules as the LO phonon peak. In the region of the TO phonon (140 to 180 cm−1) a two-peak structure occurs with the peaks labeled β and γ. This entire structure shows the overall polarization selection rules for the TO phonon.
