. Parity plot of the predicted versus reference values of ln γ ∞ i,j using the SM12 universal solvent model for the case where water was the solvent and water was the solute, as indicated. The blue lines corresponds to the y = x line, and the dashed blue lines correspond to ±1.1 and are drawn as a reference. The reference values are from "Yaws' Handbook of Properties for Aqueous Systems" . In the top pane we present results when ∆G self i,i was predicted using the SM12 universal solvent model. In the bottom pane we present results when ∆G self i,i was computed using reference vapor pressure data.
