有效哈密顿算符在计算含氧双原子分子~4∑态转动及超精细能级中的应用

Application of Effective Hamiltonian in Calculating the Rotational and HyperfineEnergy Levels of ~4∑ States for Oxygenic Diatomic Molecules

本文将 Lindgren 用于分析原子超精细结构的有效哈密顿算符理论应用到分子体系,导出了计算含氧双原子分子~4∑态转动及超精细能级的有效哈密顿算符及其矩阵公式,具体用微机计算了VO分子C^4∑^-(ν=0)态的转动及超精细能级,计算结果与实验数据基本相符。

The effective Hamiltonian,originally used in studying the atomic hyperfine structure by Lindgren,has been applied to molecules in this paper.The effective Hamil- tonian and its matrix elements for calculating the rotational and hyperfine energy levels of the ~4∑ states for oxygenic diatomic molecules have been derived,and speciffically, the rotational and hyperfine energy levels of the C ~4∑^-(V=0)state of VO have been calculated through computer.The results are in quite good agreement with the experi- mental data.
