The electronic spectrum of Au3+ and Au3N2O+ — •Marko Förstel1, Karim Saroukh1, Kai Pollow1, Este A. Najib1, Alice Green2, Stuart Mackenzie2, and Otto Dopfer1 — 1Institut für Optik und Atomare Physik, Technische Universität Berlin, Germany — 2Department of Chemistry, University of Oxford, Oxford, UK
In this talk we present our latest findings on the optical spectra of Au3+ and Au3N2O+ clusters. By using our recently enhanced setup we are able to record the optical spectra of very dilute targets in a quality that is sufficient to resolve vibrational progressions [1,2]. This allows comparisons to TD-DFT calculations on a hitherto unavailable precision. This is especially interesting in the case of gold, where theoretical models tend to have difficulties due to relativistic effects, spin-orbit coupling, and the participation of d electrons in bonding and charge*transfer effects. Thus our results will lead to a better understanding of electronic structure and the resulting catalytic properties of Au at a molecular level.
