The Willitsch Group - Cold and Controlled Molecules and Ions

Welcome to the Cold and Controlled Molecules and Ions group at the University of Basel led by Prof. Stefan Willitsch. Our research is concerned with the preparation and control of cold molecules and molecular ions and their applications in both chemistry and physics. On this website, you can find information about our group, our research, our teaching and opportunities to join us.
