Abstract: Two-LO-phonon resonant Raman scattering has been performed on pure and doped CdS and ZnSe samples and the results are analyzed in terms of excitonic theory assuming correlated electron-hole pairs as intermediate states in the transition process. Good agreement with experimental results is found. The excitons involved in the intermediate transitions are short lived for the doped samples compared to the pure sample. The resonance profile for the doped samples can be better explained by considering the involvement of excitons with larger magnitudes of k.
