The spectrophotometric solvent-sorting method for determining the free energies of transfer for individual ions, AG:(i), from water into a mixture of water and cosolvent has now been applied to cosolvents which increase the dielectric constant and enhance the solvent structure when added in small concentrations to water. The spread of AGY(i) values found, uiz. AG:(i) for i = a cation is negative and AG;(i) for i = an anion is positive, is similar to those found in mixtures where the cosolvent decreases the dielectric constant and enhances the solvent structure or increases the dielectric constant and decreases the solvent structure. Values for AG:(i)e, the free energy of transfer of the charge alone, are found for some large organic anions.
