✦ Synopsis

The optical spectroscopic properties of 1-naphthol*B, clusters (B=H20, D20, CH30H, 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=NH,, while no transfer is observed for B = CH30H up to n z 26, nor for HrO or DrO clusters up to n ii: 40. The occurrence and cluster size dependence of proton transfer are mainly determined by the proton afftnity of B. and by the electrostatic stabilization of the microsolvated ion pairs.
