Pressure Dependence of the Raman Scattering in CuCl to 37 Kbar
Raman scattering in CuCl has been the subject of many studies which were in part motivated by its anomalous transverse optic (TO) region .** 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.
