Short summary
A description of the formation of secondary organic aerosol requires the prediction of the partitioning equilibrium of organic compounds with multiple functional groups between gas and organic particle phase. While this is typically done by predicting both the saturation vapour pressure and the activity coefficient in the organic particle phase, we demonstrate here that it is feasible to predict the partitioning equilibrium directly. This direct approach has greater precision.
