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:

(a) the cavitation energy of formation of the hole which preserves the dissolved species in the solvent;
(b) the orientation energy of partial orientation of the dipoles;
(c) the isotropic interaction energy of electrostatic and dispersion origin; and
(d) the anisotropic energy of specific interactions, e.g.hydrogen bonds, donor-acceptor interactions etc.
