Electron spin resonance spectrometer

• Subject Area: Molecular Chemistry
• Term: Funded in 2025
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 553274770

At the Institute for Inorganic Chemistry of the Georg-August-Universität Göttingen, an electron spin resonance (ESR) spectrometer is to be installed or modernized under the direction of the newly appointed W1 professorship (tenure-track W2) for "Reaction Mechanisms of Inorganic Molecular Chemistry." Electron spin resonance spectroscopy is the established method for characterizing paramagnetic compounds. In classical inorganic molecular chemistry, it encompasses the characterization of reaction intermediates to elucidate reaction mechanisms of compounds of main group elements and transition metals. Furthermore, there are application fields in the area of bioinorganic chemistry to classify complex molecules with multiple spin centers, understand molecular magnetism, and describe electron transfer processes. In this context, the device will be used by the participating research groups, especially in the field of catalytic C–H activation processes with open-shell main group compounds using redox-active ligands, and for the characterization of various paramagnetic transition metal oxo-, hydrido-, and nitrido-complexes within complex reaction cascades, as well as for the structural elucidation of organic radicals.
