本论文主要研究将Hartree-Fock理论和Kohn-Sham密度泛函理论计算的分子间相互作用能分解为物理意义上的贡献。虽然没有唯一的方法来执行这种能量分解分析(EDA),但可以根据形式属性,物理内容和描述能力来判断这些方法。在整个这项工作中,我们评估和解决的弱点,绝对定域分子轨道(ALMO)能量分解方案,开发一个新的计划与条款描述五个不同的物理贡献:永久静电,泡利排斥,交换相关,极化和电荷转移。此外,该方案具有许多理想的形式属性,满足我们在引言中概述的良好EDA方法的所有标准。
This thesis is concerned with the decomposition of intermolecular interaction energies computed by Hartree-Fock theory or Kohn-Sham density functional theory into physically meaningful contributions. While there is no unique way to perform this energy decomposition analysis (EDA), such methods can be judged based on formal properties, physical content, and descriptive power. Throughout this work we assess and address the weaknesses of the Absolutely Localized Molecular Orbital (ALMO) energy decomposition scheme to develop a new scheme with terms describing five distinct physical contributions: permanent electrostatics, Pauli repulsion, exchange-correlation, polarization, and charge transfer. This scheme moreover has many desirable formal properties, satisfying all of the criteria for a good EDA method that we outline in the introduction.
