Spectroscopy and Theoretical Calculations on Molecular Compounds

Our group possesses a strong expertise in spectroscopy and theoretical investigations of molecular compounds. Our favorites objects are paramagnetic metal complexes, spin-coupled species and compounds featuring open-shell radical ligands. The experimental data obtained from crystallography, electronic absorption, IR, Raman, NMR, EPR, Mössbauer spectroscopy and magnetic measurements are in detail analyzed, explained and correlated with corresponding calculations on density functional theory (DFT) level. We use this approach in our joint projects helping others to understand their molecular systems with non-trivial electonic structures and intriguing spectroscopic properties.
