Inside Cover: The Optical Spectrum of Au2+ (Angew. Chem. Int. Ed. 48/2020). Issue 48 (13th October 2020) - Förstel, Marko
Abstract : The first optical spectrum of Au2 + derived by electronic photodissociation is analysed with quantum‐chemical calculations by M. Förstel, R. Mitric, O. Dopfer, and co‐workers in the Communication on page 21403 . The high‐resolution spectrum displays highly irregular vibronic structure as a result of multiple strongly coupled electronic states. Understanding the electronic structure of this seemingly simple H2 + ‐like diatomic radical cation of catalytic relevance requires sophisticated treatment including multireference methods, spin–orbit coupling, and relativistic corrections.
