    • The small negative frequency in both structures corresponded to a torsional motion of the methoxide anion. Attempts to eliminate the negative eigenvalue in both cases were not fruitful. Many similar conformations within a small energy range (<0.2 kcal/mol) were found, indicating that both structures were "loosely" bound.

    • Meot-Ner and co-workers have obtained results that appear to show that simple electrostatic arguments are adequate for some cationic systems. For example, see ref 4. These types of models have not been shown to have the same level of success for anionic systems. See refs 76 and 77.

    • Clearly, charge distributions are perturbed in the ion-molecule complex, and charge-transfer effects may be important. See: Weinhold, F. J. Mol. Struct. (THEOCHEM) 1997, 398-399, 181-197. Recent experimental work has suggested that neutral hydrogen bonds may have partial covalent character. (See: Cornilescu, G.; Hu, J.-S.; Bax, A. J. J. Am. Chem. Soc. 1999, 121, 2949. Isaacs, E. D.; Shukla, A.; Platzman, P. M.; Hamann, D. R.; Barbiellini, B.; Tulk, C. A. Phys. Rev. Lett. 1999, 82, 600-603). However, electrostatics provide a good qualitative model for understanding the interaction.

    • note
    • The interaction of the dipole of the substituent with the dipole of the hydrogen bond donor is small compared to their respective interactions with the charge. A simple estimation using Coulomb's law and ab initio point charges suggests that this interaction is only ∼5% of the total attractive electrostatic potential.
