摘要: 化学反应过程中的过渡态结构及氢键的拓扑性质,是近年来刚刚涉及的课题,本文讨论了文献[1]的方法对偏离平衡构型的过渡态结构及超分子体系的可用性问题及对计算精度较敏感的电子密度拉普拉斯量的拓扑特性。

关键词: 量子拓扑, 电子密度, 拉普拉斯量

Abstract: The topological properties of hydrogen-bond, the bond variation of transition structures on reaction path and the characters of the Laplacian super-surface of electronic density are discussed. The calculated results based on the semi-empirical method in this paper have good linear correlativitic-s with those of ab initio calculation.

Key words: Quantum topology, Electronic density, Laplacian amount
