Welcome to the EPR Facility


Please follow all new guidelines outlined in the COVID 19 - Phase 1 operations document.  Users should also review the Chemistry Department's Guidelines for working in the building.

Rervations for the EPR (on FACES) are required before you can work in the laboratory.

The Facility will be operating at partial capacity, but should provide the support needed for the level of research in Phase 1.  Email NMR staff (nmrstaff@chem.wisc.edu) if you have questions about procedures as stated above, or experience problems on the instruments.




Electron paramagnetic resonance (EPR)  spectroscopy is a technique for studying materials with unpaired electrons. It is particularly useful for studying metal complexes or organic radicals. 

EPR spectroscopy is used in various branches of science, such as biology, chemistry and physics, for the detection and identification of free radicals and paramagnetic centers. It is very sensitive and specific for studying both radicals formed in chemical reactions and for understanding the mechanisms for chemical reactions.
