摘要: 能量分解分析方法是一种研究分子相互作用的定量分析理论方法,在分子自组装、药物设计、化学反应机理、力场发展等各个领域得到广泛应用。现有化学本科教材对分子相互作用的讲授过于浅显,逐渐不适应现在化学系本科的培养要求。为深化大学本科学生对分子相互作用的认知,本文简述了能量分解分析方法的基本概念,介绍了具有代表性的广义Kohn-Sham能量分解分析(GKS-EDA)方法及其在六聚水多体效应中的应用。

Abstract: Energy decomposition analysis (EDA) is a quantitative theoretical method for studying molecular interactions. It has been widely applied in various fields including molecule self-assembly, drug design, mechanism of chemical reactions, and development of force fields. The existing undergraduate chemistry curriculum, however, often provides superficial explanations of molecular interactions, sometimes with inconsistencies. To deepen undergraduates’ understanding of molecular interactions, this article briefly outlines the basic concepts of EDA and introduces the representative GKS-EDA method, along with its study of multi-body effects in hexamer water systems.

Key words: Energy decomposition analysis, Water cluster, Many-body effect
