✦ Synopsis

Accurate hydrogen-bond dissociation energies were determined for gas-phase hydrogen-bonded complexes between I-naphthol or I-naphthol-d, and H,O, CH,OH, NH, and ND,, using the stimulated emission pumping-resonant two-photon ionization spectroscopy technique in supersonic jets. The hydrogen-bond dissociation energies obtained for the electronic ground state are D, = 2035 f 69 cm-' for 1-naphthol H,O, 2645 f 136 cm-' for I-naphthol . CH,OH, 2680 k 5 cm-' for 1-naphthol . NH, and 2801 k 14 cm -' for I-naphthol-d, ND,, respectively. Upon electronic excitation to the S, state the binding energies increase by approximately 8%.

It is found that the triplet-triplet energy transfer (ET) reaction between triplet benzophenone ('BP\*) and l-naphthol (ROH) is competitive with the hydrogen atom abstraction (HA) reaction. The rate constant of ET is enhanced with an increase of solvent polarity while that of HA is reduced. A possib
