密度泛函理论中的非共价相互作用

Noncovalent Interactions in Density-Functional Theory

Gino A. DiLabio, Alberto Otero-de-la-Roza

摘要:

非共价相互作用在描述软物质,包括具有重要技术意义的材料和生物分子中是必不可少的。在密度泛函理论中,通常的方法不能描述色散力,这是非共价结合相互作用的重要组成部分。在过去的十年里,在密度泛函理论的框架内,在发展精确和计算效率高的方法来描述非共价键合系统方面取得了很大的进展。在这篇综述中,我们从化学和教学的角度对该领域进行了介绍,描述了计算色散能的不同方法,并比较了它们的准确性,复杂性,受欢迎程度和一般可用性。这篇评论应该是有用的新人谁想要了解更多关于非共价相互作用和目前可用的不同方法来描述他们使用密度泛函理论。

英文摘要:

Non-covalent interactions are essential in the description of soft matter, including materials of technological importance and biological molecules. In density-functional theory, common approaches fail to describe dispersion forces, an essential component in noncovalent binding interactions. In the last decade, great progress has been made in the development of accurate and computationally-efficient methods to describe noncovalently bound systems within the framework of density-functional theory. In this review, we give an account of the field from a chemical and didactic perspective, describing different approaches to the calculation of dispersion energies and comparing their accuracy, complexity, popularity, and general availability. This review should be useful to the newcomer who wants to learn more about noncovalent interactions and the different methods available at present to describe them using density-functional theory.
