Committor analysis applied to configurations containing “frozen”
(identical) solvent coordinates in (a) the first, (b) the first two,
and (c) the first three solvation shells, and properly equilibrated
outer shells. In each figure, the colors distinguish between different
sets of frozen solvents, chosen near the associated state (red), transition
region (green), and dissociated state (blue). When freezing the first
three solvation shells on a larger system of N =
905 water molecules, the committor distributions are not as tight
(inset of panel), further demonstrating that solvent effects on dissociation
are long-ranged.
