✦ Synopsis
EIficicnt cxci~cd-sra~e proron rransfcr was dcrected by a combinalion of laser specrrosc4pic rechniqucs (laser-induced lluorcscence.. rcsonan~ twepholon ionization) in neutral microsolvenl clusrers a-naphthol.(NH3),,. which were synthesized and cooled in supersonic expansions. Exited-stare zwillerions a-naphtholale-.(NH>)"-H+ are formed for n 2 4. bu[ not for n = 1-3.

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,
Recently, the excited state proton transfer has been reported in jet-cooled methanol complex of 3-hydroxyflavone ( Dawes and Wallace. However, selective excitation of the methanol cluster bands longer than the origin band ( 356.12 nn 3-HF demonstrates that no excited state proton transfer takes plac
