本文研究了对称分子LCAO-MO的久期矩阵的结构特征,指出凡具有一定对称性的分子,即可利用对称性对其LCAO-MO久期行列式进行因子分解,使其本征值谱的计算简化.为了便于写出LCAO-MO久期矩阵,引进了多重点图.

The characteristics of LCAO-MO's secular matrioes of symmetric molecules have been investigated.The symmetry properties of the molecule can be utilized to factorize the secular determinant and simplify the calculation of the eigenvalue spectra.In order to write down the LCAO-MO's secular matrices more easily,we have introduced the multiple point into the graph representation of the molecule.
