Optical Properties of Gold Cations — •Marko Förstel¹, Kai Pollow¹, Taarna Studemund¹, Nikita Kavka², Roland Mitric², and Otto Dopfer¹ — ¹Technische Universität Berlin, Berlin, Deutschland — ²Universität Würzburg, Würzburg, Deutschland

The scientific interest in gold clusters and nanoparticles is very high, especially due to their manifold catalytic properties. In order to understand these in detail, it is necessary to have precise knowledge of the electronic structure of gold-containing systems. We probe the optical properties of small gold clusters in unprecedented detail using highly sensitive photodissociation spectroscopy and compare our results with various theoretical methods to provide a better understanding of these systems. In this talk we summarize our findings on Au₂⁺ [1,2], Au₃⁺ and Au₄⁺ [3,4] clusters.
