Webb14 mars 2024 · 自洽反应场 (self-consistent reaction field, SCRF) 假设一个极性溶质分子位于极性溶剂中，极性溶剂会产生电场，称为反应场。这个反应场会使溶质的电荷分布和气相波函数发生改变，产生一个诱导偶极，而改变之后的溶质的极性又会再影响溶剂的极性，如此反复。能使溶质的电荷分布和反应场之间达到自洽的模型都称为自洽反应场模型 … Webb12 okt. 2015 · Item is a solvent name chosen from the list:Water or H2O, Acetonitrile or CH3CN, DiMethylSulfoxide or DMSO, Methanol or CH3OH, Ethanol or CH3CH2OH, Isoquinoline, Quinoline, Chloroform or CHCl3, Ether or DiEthylEther or CH3CH2OCH2CH3, DiChloroMethane or MethyleneChloride or CH2Cl2, DiChloroEthane or CH2ClCH2Cl, …

WebbA good suggestion is to define the solvent parameters as a linear combination of the solvents in the proportions of the mixture. So for toluene:water in a 4:1 mix use 4/5 of the toluene values plus 1/5 of the water values.
