摘要: 自70年代起,Handy[1]等,用变分法计算了H2、SO2等分子的振动-转动光谱,所得结果与实验吻合。但因在于计算久期行列式元素的积分,其计算方法不易推广。

关键词: 阶梯算符, 振动-转动光谱, 臭氧, 甲醛

Abstract: One program has been developed for the variational calculation of vib-rationrotational energy levels of non-linear polyatomic molecules. The elements of the secular equation are computated by Huber's Ladder operator method. With this program the vibration-rotational spectra of Ozone and Formaldehyde have been calculated. Good agreement between the theoretical and exerimental results is obtained.

Key words: Ladder operator, vibration-rotational spectra, Ozone, Formaldehyde
