Webb28 mars 2024 · A 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. It is recommended to use the SCRF=SMD approach here, but that is not recommended for properties other than … Webb17 feb. 2024 · Calculation of Solvation Free Energy.
