分子轨道图形理论中对称面定理的扩展

An Expansion of the Theorems of a Symmetry Plane in Graph Theory of Molecular Orbitals

对唐敖庆教授和江元生教授建立的对称面定理做了一定的扩展，引进了原子轨道对称性的概念。

In this paper, the theorems of a symmetry plane, established by professor Tang Aoqing and professor Jiang Yuansheng, were expanded in a certain extent. The conceps ofthe symmetry of atomic orbitals were inducted. The expanded theorems of a symmetry planecan apply to the complex systems, including transition metals and non-adjacent interaction.
