i,j Calculator To facilitate the use of the SM12, SM8, and SMD solvation models to predict γ ∞ i,j and ultimately phase equilibrium, we are actively developing HTML (HyperText Markup Language) based software that can run in a web browser. The software is currently housed on GitHub at: . For the 148 molecules for which QChem 5.1.2 has SMx parameters (which excludes iodine and carboxylic acid containing molecules), the user can select any of the 148 molecules to form a binary pair and compute ∆G self i,i , ∆G solv i,j , and γ ∞ i,j for each component. The QChem 5.1.2 calculation results used by the software were generated in the present study. The software will continue to be developed with additional features added.
