Molecular Systems
Exploring Molecular Reactions and Quantum Dynamics
The group of Roland Wester studies the physics and chemistry of molecules and their dynamics under highly controlled conditions. For example, we explore the reaction mechanisms of ion-molecule reactions. We are particularly interested in exploring the importance of quantum dynamics in molecular collisions and chemical reactions. Furthermore, we develop methods to control and manipulate molecular interactions using lasers and traps.
Our key research areas are:
- Quantum state-resolved reactive scattering of molecules and ions
- Collisions and photofragmentation of interstellar molecules
- Spectroscopy of cold trapped molecular ions
