%0 Journal Article %T About the Hydration of Mg++: A Quantum DFT Study %A Martine Adrian-Scotto %A Diana Vasileva %A Georges Mallet %A Dan Vasilescu %J Internet Electronic Journal of Molecular Design %D 2004 %I %X The hydration of magnesium dication is studied using the DFT method BPW91/6-31G(d,p), which gives remarkable results for the reproduction of the infra-red spectrum of liquid water. The enthalpies and the Gibbs free energies of Mg++ hydration are computed using the standard and the cluster procedures, up to eight added molecules of water. The entropic contribution to the hydration phenomenon is discussed using frequency analyses. %K hydration %K magnesium cation %K hydration shell %K thermodynamics %U http://www.biochempress.com/av03_0400.html
