Abstract

Covington's nonstatistical distribution of solvate species theory of preferential solvation is used to analyze 205 Tl chemical shift data for 0.005M TlNO 3 in nine binary solvent systems. The theory quite adequately fits the experimental data, and equilibrium constants and free energies of preferential solvation are obtained. The effect of choosing different values for the solvation number is investigated and found to be slight except for systems involving DMSO, 3 where decreasing the solvation number from 6 to 3 improves the fit to experimental data.
