The solvation free energy computed for each SAMPL7 molecule is summarized in tables S1, S2, and S3 of the Supporting Information for water, neat 1-octanol, and water-saturated 1-octanol, respectively. In all cases the (total) solvation free energy is broken down into its electrostatic (m = 10 to 14) and LJ (LJ, m = 0 to 10) contributions. The LJ contribution is taken as the change in free energy in going from the non-interacting ideal gas state (m = 0) to fully interacting LJ interactions (m = 10). The electrostatic contribution is taken as the change in free energy of going from the state with fully interacting LJ interactions but no electrostatic interactions (m = 10) to fully interacting LJ and electrostatic interactions (m = 14). In tables 1 and 2 we summarize the computed octanol/water partition coefficient using both neat 1-octanol (log 10 P o/w 1 ) and water-saturated 1-octanol (log 10 P o * /w 1 ), using the TIP4P and TIP4P/2005 water models, respectively. The predictions are additionally broken down into their electrostatic and LJ contributions by using the respective contribution of the solvation free energy. In table 1 we additionally summarize the experimental values provided by the challenge organizers after the close of the challenge .
