    • note
    • Polarity changes are calculated on the basis of the maximally localized Wannier Functions (see computational section), which by definition are not suited to describe delocalized bonds. Thus, our analysis cannot be extended to tyrosine-ring CC, CO, and OH bonds, which are partially or totally delocalized.

    • Electron density difference maps of CH- - -O (Gu, Y.; Scheiner, S. J. Am. Chem. Soc. 1999, 121, 9411-9422.) have shown that also this type of hydrogen bonding involves rearrangement of the charge.
