摘　　要：发展了拉曼散射的一个广义量子理论,它能同时说明非极性模和极性模的作用.在场论中,光被纵光学和横光学模的拉曼散射能在一个统一的理论框架内描述.Although the classical and quantum theories of Raman scattering of light by optical phonons have been well established, the papers genarally emphasized on some particular aspects of the scattering. For this reason, we need to develop a general quantum theory of Raman scattering, taking account of both nonpolar and polar modes. In our quantum theory, Raman scattering of light by longitudinal and transverse polar modes can be described within a unified theoretical framework.
