双原子分子的对称性与离解极限

Diatomic Molecular Symmetry and Dissociation Limit

要正确深入分析分子在不同电子状态下的势能行为,就必须分析分子的对称性和离解极限。文章在讨论了双原予分子的相关对称性及其相互联系的基础上,应用原子分子反应静力学方法讨论了双原子分子对称性的演化规律和离解极限,并具体分析了几个典型的双原子分子的离解极限,分析的结果与实验的结果一致。

Symmetry and conservation are very important for correctly analyzing diatomie molecular symmetry and dissociation limit. In this paper, relative symmetry and its possible change, dissociation limit of diatomie molecule are discussed with atomic and molecular reaction statics （AMRS）. The symmetries and dissociation limits of several topical diatomie molecules are analyzed by AMRS approach. The analytical results agree with the results of the experiment and other theories.
