一般电解液里面都是单独计算的吗?不需要考虑其存在的环境?
The simulation of liquid environment is considered by using the continuous polarization medium method
(dielectric constant=20.5). Frequency analyses were carries out at the same way to verify the obtained optimized stationary
point.

从这个图看不出共存什么的。看起来就是每一个分子单独计算一次。得到分子轨道的能量画在图上而已。

不是不考虑,而不是说把所有溶质溶剂分子放在一起算。而只是把溶液环境抽象成了一个连续介质, 带有一个特定的介电常数。也就是所谓的隐式溶剂模型。既然这个句子里没有说哪种隐式溶剂模型。那如果用高斯的,那应该就是默认的pcm 模型。 也就是说你单独计算每一个分子的时候加上溶剂模型就行了。它就可以一定程度上算是考虑了溶液环境。 调用溶剂模型的关键词是scrf 并且可以根据文献的给你的介电常数20.5来设置溶剂。
