Molecular Structure and Dynamics

Our group combines and integrates mass spectrometry with IR spectroscopy, enabling us to obtain infrared spectral fingerprints for mass-selected ions inside the mass spectrometer. We apply infrared ion spectroscopy in various analytical challenges of identifying molecular structures of low-abundance compounds within complex mixtures, e.g. in biomarker discovery. In more fundamental studies, we investigate molecular spectra and structures of ionized molecules, e.g. to pin down the molecular structure of MS/MS product ions or for applications in astrochemistry.
