摘要：

Vibronically induced conformational relaxation is reported between two distinct structures of the jet-cooled cluster coumarin 151/(H2O)(2). The process involves transfer of the water dimer in the electronically excited state over a distance of approximate to8 Angstrom between sites on the coumarin molecule, governed by an activation energy of 60 cm(-1).
