Abstract
A study has been made on the shifts in the spectrum of the S 1←S0 transition in benzene molecules transferred from low-density vapor to dilute, liquid solutions in order to estimate the geometrical parameter R v 1u, characterizing the distribution of the solvent molecules around the solute. The R v 1u parameter is a measure of the repulsion between the solution components. Effective radii have been derived for the fluctuation cavities whose existence in the pure solvent is necessary to the dissolution. The free energy, enthalpy, and entropy of the boundary between a solute molecule and the solvent have been derived for aqueous solutions. The energy of the hydrogen bonds in pure water has been estimated.
