✦ Synopsis

Stimulated RAMAN scattering in molecular crystals is quantum theoretically described as stimulated polariton scattering. The quantum theoretical treatment of molecular crystals is given within the framework of a second quantization described in an earlier work. I n the HEISENBERG picture the equations of motion for the operators of the polaritons are derived and specialized for RAMAN scattering. By supposing quasi-stationary behaviour the operators of the polaritons that are mixtures of phonons and photons are eliminated. The resulting equations are shown to have the same structure but a generalized physical meaning as those derived by GROB on other way.
