关键词: 团簇, 计算化学, 过渡态搜索, 电子定域化函数, 芳香性

Abstract:

This paper explores and expands an undergraduate inorganic chemistry problem in depth from the perspective of quantum chemistry. It sheds light on the P42− clusters of which the structures and transition states were searched and the Gibbs free energy of the stable configuration was calculated. Meanwhile, we analyzed the clusters and their transition states, calculated the electron localization function (ELF), elaborated the delocalization of the system through basin population and then discussed the characteristics of lone pair aromaticity of the P42− clusters in the viewpoint of quantum chemistry.

Key words: Cluster, Computational chemistry, Transition state search, Electron localization function, Aromaticity
