Abstract
\begin{wrapfigure}{r}{0pt} \includegraphics[scale=0.66]{abstract_fig.eps} \caption{Electronic spectrum of \ce{Au2+N2}.} \end{wrapfigure} The binding motif of nitrogen on transition metals is an interesting issue. Here we present the electronic spectrum of the $\tilde{A}^2\Sigma^+ \rightarrow \tilde{X}^2\Sigma^+$ transition of \ce{Au2+N2}, which was measured via photodissociation spectroscopy. The spectrum contains a long progression, caused by symmectric and asymmetric strech vibrations. We extract harmonic frequencies, anharmonicities and cross-anharmonicities of the excited state via a Dunham expansion and harmonic frequencies of the ground state via Franck-Condon simulations. In comparison to density functional theory calculations, the observed frequencies agree well with the theory. We also discuss the binding motif of \ce{Au2+N2} in the ground and excited state. \begin{itemize} \item[{[1]}] M. Förstel, K. Pollow, T. Studemund, O. Dopfer, Chem. Eur.
