Zusammenfassung

By using time-​resolved photoelectron spectroscopy, decay of optically excited states of hydrated Au-​ mass-​selected in the gas phase was studied. Probably the pump-​photon can induce injection of an electron from auride chromophore to the H2O solvent. The cluster with 3 H2O mols. (Au-​(H2O)​3) showed a long-​living excited state with a lifetime of ∼19 ± 3 ps, whereas that of Au-​(H2O)​2 is only ∼3 ± 1 ps. The fate of an optically excited state of an ionic species can be significantly changed by the no. of H2O (solvent) mols. attached.
