solvation energy

The change in Gibbs energy when an ion or molecule is transferred from a vacuum (or the gas phase) to a solvent. The main contributions to the solvation energy come from:
  1. the cavitation energy of formation of the hole which preserves the dissolved species in the solvent;
  2. the orientation energy of partial orientation of the dipoles;
  3. the isotropic interaction energy of electrostatic and dispersion origin; and
  4. the anisotropic energy of specific interactions, e.g. hydrogen bonds, donor-acceptor interactions etc.
