solvent如何写才能等效于高斯中的SCRF(SMD,read,solvent=generic)作者Author: sobereva 时间: 2022-4-15 04:06

ORCA手册里都写明了每个参数的含义,参考着我博文写就完了
%cpcm smd true # turn on SMD
SMDsolvent "water" # specify the name of solvent from the list
soln # index of refraction at optical frequencies at 293 K
soln25 # index of refraction at optical frequencies at 298 K
sola # Abraham's hydrogen bond acidity
solb # Abraham's hydrogen bond basicity
solg # relative macroscopic surface tension
solc # aromaticity, fraction of non-hydrogenic solvent atoms that are aromatic carbon atoms
solh # electronegative halogenicity, fraction of non-hydrogenic solvent atoms that are F, Cl, or Br

谢谢sob老师,我会注意的。
我做的是离子液体的smd,
1.20的折射能找到,25的折射影该怎么估算。
2.我理解就是虽然写的是water,但是后面自定义了所有的smd参数,代替了water。那意思是这里添任何溶剂都可以吗?只要后面给出完整的参数。我替换了不同的溶剂,定义了同样的参数,能量会有不同。查了out文件
