Dynamics of Molecular Systems

Our research focuses on the physics of molecules, molecular systems with several components, and organic materials. The properties and the behavior of many substances, materials and biomolecular systems result from their molecular constituents. To understand and design their properties relies on the understanding of these constituents.

The work of our group follows two lines. One deals with processes within molecules like charge transfer, the change of electronic states, the coupling to nuclear motions, and mechanisms of chemical reactions. The other line addresses organic materials and interfaces. In these systems we investigate the dynamics of electronic excitations, charge separation, and energy and charge transport. The results are highly relevant for functional materials, organic electronic applications and solar cells. Our main experimental technique is ultrafast spectroscopy with a resolution down to 10 fs, which allows to observe the processes in real time.
