Sažetak

The experimental gas-phase acidities of a series of substituted phenols at the meta- and parapositions are interpreted in terms of electronic parameters characterizing the hydroxyl functionality. It is found that the acidities are linearly related to the theoretically derived electrostatic potentials at the atoms of the OH group. The NBO atomic charges at the same atoms correlate reasonably well with acidities.
