Many particle approach to resonance Raman scattering in crystals: Strong electron-phonon interaction and multi-phonon processes

► Raman scattering of light by crystals studied theoretically. ► Electron-electron and electron-phonon interactions taken into account. ► Structure of many phonon repetition of bands described. ► Both Raman and resonance Raman scattering covered. ► Comparisons with experimental data for CdS and ZnO crystals.
