EPR spectroscopy is an essential research tool in a variety of research fields from materials science to medicine
Applications of EPR Spectroscopy

Electron paramagnetic resonance (EPR), or synonymously electron spin resonance (ESR) spectroscopy, is a magnetic resonance technique used to study materials with unpaired electrons. Examples include free radicals, transition metal ions and multiatom clusters found in diverse areas as nanomaterials, materials science, structural biology and chemistry, food science, radiation dosimetry and medicine.

Structural and electronic characterisation of a sample by EPR spectroscopy is afforded by measuring couplings between the unpaired electrons and magnetic nuclei. Samples for study can be in the form of a powder, crystal, solution or solid with no limit on molecular size. Non-invasive EPR imaging offers the capacity to spatially locate paramagnetic molecules in small animals and bulk materials.
