Excited State Intermolecular Proton Transfer in Isolated Clusters: 1- Naphthol/Ammonia and Water

Abstract

The excited singlet state intermolecular proton transfer reaction in jet-cooled clusters of 1-naphtho1/ammonia and water is investigated employing mass resolved excitation, threshold photo-ionization, and emission spectroscopy. The 1-naphthol(NH3)3 cluster for which proton transfer is indicated has a threshold photo-ionization energy roughly 2000 cm-1 below the other 1- naphthol(NH3)3 cluster configurations. These results are employed to explain the previous discrepancy between static spectroscopic experiments and picosecond time resolved dynamic experiments concerning proton transfer in the 1- naphthol(NH3)3 cluster. Calculations of cluster geometry in 1-naphthol/ammonia and water cluster systems suggest some qualitative explanations of these observations.
