Abstract

The optical spectroscopic properties of 1-naphthol·Bn clusters (B=H2O, D2O, CH3OH, NH3 and piperidine) have been studied in supersonic molecular beams. Proton transfer to the solvent cluster occurs at n≥2 for B=piperidine and n≥4 for B=NH3, while no transfer is observed for B=CH3OH up to n≈26, nor for H2O or D2O clusters up to n≈40. The occurrence and cluster size dependence of proton transfer are mainly determined by the proton affinity of Bn and by the electrostatic stabilization of the microsolvated ion pairs.
