Figure 2.
Bond distances, spin and charge densities (in parentheses) of selected SO2, SO3, and SO4 radical adducts of DMPO and their respective conjugate acids. Also shown are the aqueous phase free energies and enthalpies of reaction (ΔG298K, aq, ΔH298K, aq in kcal/mol) at the PCM/B3LYP/6-31G**//B3LYP/6-31G* level of theory.
