Abstract Accurate hydrogen-bond dissociation energies were determined for gas-phase hydrogen-bonded complexes between 1-naphthol or 1-naphthol-d3 and H2O, CH3OH, NH3 and ND3, 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 D0 = 2035 ± 69 cm−1 for 1-naphthol · H2O, 2645 ± 136 cm−1 for 1-naphthol · CH3OH, 2680 ± 5cm −1 for 1-naphthol · NH3 and 2801 ± 14 cm−1 for 1-naphthol-d3 · ND3, respectively. Upon electronic excitation to the S1 state the binding energies increase by approximately 8%.
