Our group employs advanced preparative, spectroscopic and theoretical tools to tackle our research questions including
i) syntheses under inert conditions (gloveboxes, Schlenk techniques), syntheses under pressure or with microwave irradiations and photoreactions,
ii) UV/Vis/NIR, emission, EPR, IR and Raman spectroscopy with state-of-the-art high-end spectrometers and
iii) theoretical methods (DFT/TDDFT, CASSCF; ORCA software package) at the high-performance computing facilities in Mainz and Kaiserslautern.
