Detecting Weak Interactions between Au- and Gas Molecules: A Photoelectron Spectroscopic and Ab Initio Study
In this communication, we report a joint experimental and theoretical study of the interactions between gold anion, Au-, and an NG atom (NG ) Ne, Ar, Kr, Xe) or a molecule of O2, CH4, or H2O. Except for the Au- · · ·H2O interaction, which is comparable to strong hydrogen bonding, all of these are weak charge-induced intermolecular interactions. The observation of a weakly bound Au(O2)- complex shows the inertness of Au- toward O2, in line with the previous observation of the odd-even effect in the reactions of Aun - clusters and O2. By comparing with results of high-level ab initio calculations, we demonstrate that anion PES is a good technique for probing weak charge-induced intermolecular interactions.
