solvation

sol·va·tion

(sol-vā'shŭn),
Noncovalent or easily reversible combination of a solvent with solute, or of a dispersion means with the disperse phase; if the solvent is water, solvation is called hydration. Solvation affects the size of ions in solution, thus Na+ is much larger in H2O than in solid NaCl.

solvation

The interaction of solvent molecules with the molecules or ions dissolved in them.

Therefore the sonication effect should reflect the solvation mode of ester molecules.
In this study, the responses of the porphyrin [[pi].sup.*] [left arrow] [pi] transition energies were investigated with respect to changes in the composition of binary solvent mixtures, using nickel and freebase porphyrins with several different peripheral substituents, For mixtures in which preferential solvation is not significant, the responses of the absorption band energies were investigated with respect to functions of the solvent mixture refractive index which relate to the polarizability of the solvent environment.
The free energy of solvation AGaq, and the corresponding pKa values have been calculated by using eq.2-5.
It is interesting to observe that the SMD solvation model is powerful enough to allow discriminating between the values for the global descriptors in both solvents.

In the literature, column classification in SFC has been carried out by chemometric analysis based on linear solvation energy relationships (LSER) [3,5,11,25,29].
[DELTA][G.sub.np] is the nonpolar solvation contribution and was calculated with constants 0.0072 kcal [mol.sup.-1] [[Angstrom].sup.-2] for surface tension proportionality constant [gamma] and 0.92 kcal [mol.sup.-1] [[Angstrom].sup.-2] for the nonpolar free energy for a point solute [beta].
The first section is concerned with the forces holding together supramolecular assemblies of ions and begins with an overview of the history and methodology of ion solvation theory.
