Structure and Dynamics of Cold and Controlled Molecules

Welcome to the website of the independent Max-Planck Research Group focusing on the structure and dynamics of molecules and molecular complexes. We are aiming at getting deeper insight into molecular recognition processes by studying selected molecular complexes and their dynamics in the gas phase.

Our group started in January 2011, and we are jointly hosted by the Max-Planck Insitute of Nuclear Physics in Heidelberg and by the Center for Free-Electron Laser Science in Hamburg (associated with the Max-Planck Advanced Study Group).


Very recently, we finished setting up a broadband chirped-pulse rotational spectrometer. This will allow us to study the molecular parameters and structures of also larger and more complex molecules. For the dynamics studies, we combine broadband rotational spectroscopy with UV or IR laser excitation, i.e., we first pump the molecules and molecular complexes of interest with UV or IR excitation and then probe them with a broadband microwave chirp. This will reveal interesting important, for example about the isomerization dynamics of the particular species.

Our chirped-pulse broadband rotational spectrometer became operational this summer! Here you can see first results: The rotational spectrum of trifluoro iodomethane (CF₃I) as a test molecule in the 2-8 GHz range.
