Abstract

Mass-resolved excitation/ionization spectroscopy and excitation/emission spectroscopy are used to investigate the proton transfer reaction in the excited singlet state of the jet-cooled 1-naphthol (NH₃)n and 1-naphthol (H₂O)n. Results indicate no proton transfer for 1-naphthol(NH₃)₁₂ and 1-naphthol(H₂O)n and proton transfer for 1-naphthol(NH₃)n (n≥4) clusters, which is consistent with other reports,^1-3 However, 1-naphthol(NH₃)₃ exists in multiple conformations, as evidenced by the changes of the peak intensities around the electronic origin with the variations of the second-color energy in the mass-resolved excitation/ionization spectra (Fig.1).
