Spectroscopy and dynamics of excess electrons in clusters

Anionic clusters comprising solvent molecules and excess electrons can provide new insights into electron solvation in liquids, an intrinsically bulk phenomenon. This paper reviews experimental and theoretical studies of this class of clusters, focusing primarily on water cluster anions, [image omitted], but also on iodide-water clusters, I-(H2O)n, and methanol cluster anions [image omitted]. Issues of particular interest include the relationship of time-resolved dynamics in these clusters to those of bulk solvated electrons, and the nature of the electron binding motifs supported by these clusters.
