WebThe relation between a solvophobic interaction (SI) and a solute–solute radial distribution function is discussed. The SI is defined as the difference between the indirect part of the solute–solute potential of the mean force in a solvent and that in a “homomorphic” solvent. It was calculated using the RHNC-like integral equation of RISM-1 for a dilute solution of … http://www.cchem.berkeley.edu/ergrp/pdfs/papers/paper39.pdf
