As already mentioned, the Minnesota Solvation Database was used in the parameterization of the SMx universal solvent models. Its use was motivated by the desire to assess the prediction of the individual contributions, ∆G solv i,j and ∆G self i,i , and the combined effect on ln γ ∞ i,j . As a secondary test, we curated reference data from Parts 1 to 6 of DECHEMA's "Activity Coefficients at Infinite Dilution" volumes . We again restricted ourselves to binary systems for which both components were in our set of 148 molecules (solvents) for which QChem contains SMx parameters. This resulted in limiting activity coefficients for an additional 2163 systems, consisting of 117 unique solutes and 77 unique solvents. Note that as compared to the Minnesota Solvation Database wherein there was only a single entry for each unique system (i.e., solute-solvent pair), duplicates were present in DECHEMA. We retained all of the data, including duplicates, in the final set.
