AG Junior Prof. Dr. J. Meyer
Our research focuses on understanding chemical reactions at the molecular level. To this end, we investigate the dynamics of chemical reactions under single impact conditions in the gas phase. The focus is on the activation of small molecules, e.g. hydrogen or methane, by transition metal ions or small clusters.
In the experiment, we cross an ion beam with a molecular beam of the neutral reactant and deactivate the resulting products using a velocity map imaging spectrometer. Atomic mechanisms then lead to features in the measured velocity distribution
- Effects of electronic states on reaction dynamics of bond activation of small molecules by transition metals
- Dynamics of ion-molecule reactions with a focus on CH bond activation or the reaction of activated hydrocarbon centers
AG Prof. Dr. C. van Wüllen
The van Wüllen working group focuses on the following topics, among others:
- Development of relativistic quantum chemical methods
This includes the development of two-component relativistic approaches that treat the spin-orbit interaction self-consistently. These are needed, among other things, to describe transactinides ("superheavy elements").
Transition metal catalyzed organic reactions
In cooperation with the experimental group of J. Christoffers in Oldenburg, we are investigating Fe(III) and Cu(II) catalyzed additions of dicarbonyl compounds to acceptor-activated olefins (Michael Additon). We are investigating the extent to which the enation selectivity of the Cu(II) variant can be made more effective and which factors are responsible for this.- Magnetic properties of transition metal complexes
In cooperation with exp. groups, the aim is to understand the magnetic (exchange) coupling, especially where the rules of thumb fail. The calculation of magnetic anisotropy - a property that is closely linked to zero-field splitting - is a particular challenge for multinuclear complexes with antiferromagnetic coupling.
