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.

Kommentar zur Publikation:	Erratum to ‘Relaxation dynamics... ': We included above the corrected author list. One of the co-authors, Susanne Pietsch, was missing in the originally published Letter. The main contributions from Susanne Pietsch were the photoelectron spectra of Au−(H2O)m with m = 0–6 shown in Figure 1 measured with a photon energy of 7.9 eV. These data were critical to understand the data of the femtosecond time-resolved photoelectron spectroscopy. [Chemical Physics Letters ; https://doi.org/10.1016/j.cplett.2014.01.032]
