Gold nanoclusters have surprising and interesting optical and catalytic properties. Understanding of the electronic structure of the prototypical Au 2 + dimer gives us the tools we need to understand more complex systems that are dominated by the strong relativistic effects and spin–orbit coupling of gold. The first optical spectrum of the low‐lying excited electronic state of cold Au 2 + obtained by Ar tagging is exceptionally well resolved, and its surprisingly simple vibronic structure provides detailed information about structure and bonding in the ground and first excited states. More information can be found in the Communication by M. Förstel, O. Dopfer et al. (DOI: 10.1002/chem.202102542).
