Abstract

This review focuses on a combination of ab initio molecular dynamics (aiMD) and NMR parameters calculations using quantum mechanical methods. The advantages of such an approach in comparison to the commonly applied computations for the structures optimized at 0 K are presented. This article was designed as a convenient overview of the applied parameters such as the aiMD type, DFT functional, time step, or total simulation time, as well as examples of previously studied systems. From the analysis of the published works describing the applications of such combinations, it was concluded that including fast, small-amplitude motions through aiMD has a noticeable effect on the accuracy of NMR parameters calculations.

摘要

本综述聚焦于从头算分子动力学(aiMD)与使用量子力学方法进行的核磁共振(NMR)参数计算相结合的研究。相较于通常应用于0 K下优化结构的计算方法,阐述了这种方法的优势。本文旨在方便地概述所应用的参数,如aiMD类型、密度泛函理论(DFT)泛函、时间步长或总模拟时间,以及先前研究系统的实例。通过对已发表的描述此类结合应用的作品进行分析,得出结论:通过aiMD纳入快速、小幅度运动会对NMR参数计算的准确性产生显著影响。
