【Abstract】 In this paper,We in a half quantitative way consider the delocalization of the π bonds of some inorganic threeatomic molecules (or ion ) in the light of the theory of groups and Huckel π-electron theory.The energy leves are given out for π molecular orbitals,and results are employed to explain the stable constitutlon and magnetic of these molecules.更多还原
