Abstract
G2 theory calculations were performed on [H_(3)SiO_4]^−, [H_(4)SiO_4], [H_(3)AlO_4]^2−, [H_(4)AlO_4]^− and [H_(5)AlO_4]. Molecular structures, atomic charges, and infrared spectra at the HF/6-31G* and MP2/6-31G* levels are compared. The influence of polarization and diffuse functions on the structure of [H_(3)SiO_4]^- is also examined. Basis set and electron correlation effects on potential energies are assessed by comparing various levels of theory. Proton affinities of these gas-phase molecules and related mineral surface species are predicted based on corrections for cluster-size effects.
