(A and B) The PMFs between two M0-like neutral solutes in (A) water and (B) 40% by mass ethanol solution at various z locations highlight the generality of the interface-dominated solute association on the vapor side of the interface. The solutes have strong attractive Lennard–Jones interactions with solvent molecules, but have repulsive Weeks–Chandler–Andersen (44) interactions with each other.
