摘要
本文利用U(4)群代数描述双原子分子振转谱的对称性质,利用群论计算了H_2分子受激喇曼散射跃迁矩阵元,绘出了受喇曼散射的截面与增益系数,较好地与实验结果符合.
The symmetry of rotation-vibration states of diatomic molecules are discribed by means of group U (4). The matrix elements of stimulated Raman scattering are calculated by means of group theory approach. The cross sections and gain coefficients of stimulated Raman scattering are given. The results agree with the experimental values.
