摘要
本文利用群链U(4)U(3)O(3)描述双原子分子N_2和O_2振转谱的对称性质,并利用群论方法计算了N_2和O_2分子转动喇曼散射的跃迁矩阵元,给出了它们的转动喇曼散射的截面。结果与实验较好地符合。
The symmetry of rotation-vibration states of diatomic N2 and O2 are disoribed by means of the chain of subgroups U(4) U(3) O(3) . The transition matrix elements of rotational Raman scattering are calc ulated by means of the group theory approach. The cross section of rotational Raman scattering are given for N2 and O2. The results are in good agreement with the experimental values.
