    • note
    • Here we cannot talk of same pH, since we do not control it, but we have the same conditions in the sense of same initial structures, particles, number of electrons, and number of solvent water molecules. In this sense, the conditions are the same for each couple and the differences are to be taken into account system by system.

    • note
    • Calculations in clusters, even including more than first hydration shell have intrinsic ambiguities in determining the existence of an apical bond. In fact in bulk water, a molecule is in competition between being hydrogen bonded with the oxo atoms or with oxygen atoms of the bulk. The bulk not being present in cluster calculations excludes this latter choice such that the apical bond is the only possible interaction.
