    • For the two-methane PMF calculation we have conducted, wherein snapshots of water configurations were taken every 100 passes, the statistical inefficiency parameter s (see, e.g., Allen, M. P.; Tildesley, D. J. Computer Simulation of Liquids; Oxford University Press: Oxford, 1987) was determined to range from s ≈ 75 for low and intermediate T (below 328 K) to s ≈ 35 for high T (348, 368 K). It follows that, during the course of our simulation, water configuations become uncorrelated after roughly 4000-7000 passes of sampling.

    • It is clear from Figure 1 that different φ angles define physically different sets of relative positions for the three methanes. It should also be noted that, as in our previous studies, the PMF at a given ξ,φ is defined here by the free energy of insertion at a particular spatial position. By construction, this PMF does not involve entropic free energy associated with the multiplicity of methane spatial positions sharing a given ξ,φ. In other words, the present PMF contains no "cratic" contribution arising from the configurational degrees of freedom of the methane molecules.

    • We note that Ghosh et al.'s reported anti-cooperativity at the contact minimum and cooperativity at the desolvation barrier do not appear to add up to the values summarized in Table 2 above.
