标题: 求问6-311+g**算单点能的精度够吗 [打印本页] 作者Author: littleear 时间: 2024-9-8 11:53 标题: 求问6-311+g**算单点能的精度够吗 前阵子投了一篇文章,用m06-2x/6-31g*做有机物的结构优化,m06-2x/6-311+g**算的单点能,但是有个审稿人说
The justification for the DFT calculation method was insufficient, which could lead to inaccurate conclusions. For example, when calculating the single-point energy of pollutant molecules, the M06–2X/6–311+G(d, p)/SMD method is used, but the accuracy of this method has not been verified.
我看文献中大部分都是用的6-311++g**算的单点能,但是社长说不要随便给H加弥散函数,所以我当时才用的6-311+g**,请问这个精度真的不够吗?如果够的话,有什么文献可以佐证吗?
非常感谢各位!

单点用def2-TZVP多好,下文明确说了
