Multifrequency EPR Spectroscopy and Spectroelectrochemistry

EPR spectrum

EPR spectrum

Synthesizing and characterizing paramagnetic compounds is one of the priorities in our group. These compounds, which sometimes get a step-motherly treatment from chemists, can be characterized through EPR spectroscopy. Additionally, we routinely generate short-lived radical intermediates through in-situ electrolysis, and the method of EPR spectroelectrochemistry comes in very handy for the characterization of such species. Apart from characterizing paramagnetic species, we use EPR spectroscopy also to investigate reactive intermediates of catalytic reactions that involve radical intermediates. Furthermore, EPR spectroscopy is a useful method while investigating magnetically switchable molecules. While we can perform X-band EPR spectroscopy in our own labs, high frequency EPR measurements are sometimes carried out in joint projects with our collaborators.
