COS分子红外谱的群论计算

GROUP THEORETIC CALCULATION FOR INFRARED SPECTRAL OF THE TRIATOMIC MOLECULE COS

利用Ｕ（５）模型给出了ＣＯＳ分子的振转能级，并且用标准的群论方法计算了ＣＯＳ分子的红外吸收谱线的强度。结果与实验较好的符合。

The rotation vibrational molecule COS is described by model U(5) . The transition matrix elements of the molecular levels are calculated by means of the group theoetic approach. The infrared absorption line intensities are calculated for the molecule COS. The results are in good agreement with the experimental values.
