| Summary: | The local polarity of solvent mixtures near a polar solute molecule can be very different from the mixture’s bulk polarity. A general mechanism which determines the local polarity is the “dielectric enrichment” which is described by the thermodynamic equilibrium in a solvent shell enriched in polar solvent. This equilibrium and the resulting local polarity can be described quantitatively by the balance between the electrostatic stabilization energy and the entropy of unmixing of a solvent shell enriched in polar solvent.
