ELECTRON SPIN RESONANCE (ESR) SPECTROSCOPY
www.nou.ac.inElectron spin resonance (ESR), also called electron paramagnetic resonance (EPR), is a spectroscopic technique confined to the study of species having one or more unpaired electrons. Among the large number of systems having one or more unpaired electrons, i.e. paramagnetic system, the most important ones are free radicals, transition metal ions ...

EPR spectroscopy is similar to any other technique that depends on the absorption of electromagnetic radiation. A molecule or atom has discrete (or separate) states, each with a corresponding energy.
