Department of Molecular Physics

The research in the Department of Molecular Physics focuses on the structure and the intra- and inter-molecular dynamics of molecular systems, from diatomic molecules to biological macromolecules, either in isolation or in interaction with their environment. For this, new experimental methods to manipulate and control, to characterise and to spectroscopically investigate these molecular systems are developed and exploited.

Research themes


An international team for the first time observed the formation of a metallic conduction band in electrolytes using photoelectron spectroscopy. This allowed a deeper insight into the behaviour of electrolytes and so-called dissolved or solvated electrons, which play an important role in a large number of large-scale industrial chemical processes. The work is published in Science. more

Bernd Winter, who leads the Liquid Microjet project in the Molecular Physics Department, has been awarded an Advanced Grant from the European Research Council (ERC) endowed with €2.5 million over a period of five years. more

The chemist Prof. Dr. Kevin Pagel has been awarded a highly endowed Consolidator Grant from the European Research Council (ERC). Pagel is a professor of bioorganic chemistry at Freie Universität Berlin and a visiting researcher at the Fritz Haber Institute. more

Researchers from the Fritz-Haber Institute of the Max-Planck Society in Berlin identified aluminum monofluoride (AlF) as an excellent molecule to be laser-cooled to ultra-low temperatures with a high density. Atoms have been laser-cooled with great success for over 30 years. Recently, this powerful technique has been extended to small molecules, but a major challenge remains: to increase the density of the laser-cooled molecular gas by many orders of magnitude. AlF has the potential to achieve… more
