摘要：
It is shown by means of density matrix formalism that the total expression for the third-order nonlinear susceptibility chi(3) (omega(4) = omega(1) - omega(2) + omega(3)) contains additional terms proportional to the differences or to the squared differences of permanent dipole moments of couples of energy levels. These new terms are interesting for some cases of electronic Raman transitions of polyatomic polar molecules, where their contribution to total Raman susceptibility could be significant.
