dc.description.abstractRelaxation dynamics of optically excited states of and (H2O)m were studied via femtosecond time-resolved photoelectron spectroscopy (fsTRPES). exhibits photo-dissociation into either ( + Au1) or (Au2 + ) with a time constant of 1.6 ns. One water molecule adsorbed on opened new photo-induced dissociation channel with a much shorter time constant. More than one water molecule on inhibited photo-dissociation, most likely as a result of facile dissipation of excess energy of optically excited states by nuclear motions of clusters. The photochemical pathway can be controlled by adjusting the number of water molecules interacting with the ionic species.eng
