The present work outlines the fair relationship of the computational model with the experiments on anion photoelectron spectroscopy for the gold-water complexes [Au(H2O)1≤n≤2]- that is established between the auride anion Au- and water monomer and dimer thanks to the nonconventional hydrogen bond where Au- casts as the nonconventional proton acceptor. This work also extends the computational model to the larger complexes [Au(H2O)3≤n≤5]- where gold considerably thwarts the shape of water clusters and even particularly breaks their conventional hydrogen bonding patterns. The fascinating phenomenon of the lavish proton acceptor character of Au- to form at least six hydrogen bonds with molecules of water is computationally unveiled in the present work for the first time.

The dynamics of iodide-uracil-water (I<sup>−</sup>·U·H<sub>2</sub>O) clusters following π-π* excitation of the nucleobase are probed using time-resolved photoelectron spectroscopy (TRPES). Photoexcitation of this cluster at 4.77 eV results in electron transfer from the iodide moiety to the uracil, creating a valence-bound (VB) anion within the cross-correlation of the pump and probe laser pulses. This species can decay by a number of channels, including autodetachment and dissociation to I<sup>−</sup> or larger anion fragments. Comparison of the energetics of the photoexcited cluster and its decay dynamics with those of the bare iodide-uracil (I<sup>−</sup>·U) complex provide a sensitive probe of the effects of microhydration on these species. The results are also compared with TRPES experiments on I<sup>−</sup>·U·H<sub>2</sub>O at lower pump photon energies, where both the initial photoinduced dynamics and the decay of the photoexcited cluster are qualitatively different.
