Research Highlights

  • The group develops and applies modern methods of laser spectroscopy, mass spectrometry, and quantum chemistry to characterize molecules, radicals, ions, clusters, and nanostructures. The central objective is to determine the geometric and electronic structure and the optical and chemical properties. We use intense laser sources in the IR-VIS-UV spectral range (OPO and FEL) and various cluster sources in combination with molecular beams or cryogenic ion traps. The studied systems are of central importance in the fields of solvation, biophysics, chirality, catalysis, astrochemistry and astrobiology, plasmas, planetary atmospheres and combustion, and new nanomaterials.
