分子矩树图表示及π-键级的估算

The Tree Graph Expression of Molecular Moments and the Evaluation of π Bond Grade

提出了分子矩的树图表示，并借此应用π－键级与π－电子总能量的关系及线性代数中的Ｃａｙｌｅｙ－Ｈａｍｉｌｔｏｎ定理。

We proposed the tree graph of molecular moment.Making use of the relationship be tween π bond grade and π electron energy,and the cayley Hamilton therem in algebra and the tree graphic method,we obtained the tree graph method of the eva luation of molecular moment.
