    • - time reported in ref 6c. This experimental time estimate was subsequently considerably revised upward by about 32% in ref 6a. In any event, we will see in Section 3.2 that a time extracted from experimental data, while directly related to the escape of an HOD from the anionic hydration shell, is noticeably different from the residence time of the HOD in that hydration shell.

    • One should note, however, that small water cluster and aqueous solution characteristics for anions generally differ; an example is the OH frequency shift (see: ref 22. Thompson, W. H.; Hynes, J. T. J. Am. Chem. Soc. 2000, 122, 6278.

    • note
    • At high concentrations of the salt, the countercation can even be in the first solvation shell of the anion, i.e., a contact ion pair, or the HOD could form a bridge between the two ions, i.e., a solvent-separated ion pair. In either of these cases or related variants of them, the escape process for the HOD would obviously be altered from that simulated in the present work.

    • Actually the authors of ref. 6 adopt a sum of such Gaussian random process descriptions for the bulk OH vibrations and those in the ion solvation shell. We do not adopt this route since there are, for example, issues of the differing intensities of these OH absorptions.
