Abstract

In the presence of an externally applied static magnetic field, electron paramagnetic resonance (EPR), also known as electron spin resonance (ESR), is a branch of magnetic resonance spectroscopy that uses microwave radiation to probe species with unpaired electrons, such as radicals, radical cations, and triplets. The physical characteristics of the fundamental EPR theory and techniques are similar to those of Nuclear Magnetic Resonance in many respects (NMR). The most apparent distinction is that EPR probes electron spin characteristics directly, while NMR probes nuclear spins. EPR spectroscopy has a wide range of applications, from studying the kinetics and mechanisms of highly reactive radical intermediates to obtaining information about the interactions between paramagnetic metal clusters in biological enzymes, despite the fact that it is limited to substances with unpaired electron spins. EPR may also be utilised in the semiconductor sector to investigate materials containing conducting electrons.EPR is a very helpful kind of spectroscopy for studying molecules and atoms that have an unpaired electron. Because stable compounds seldom contain unpaired electrons, it is less frequently utilised than NMR. EPR, on the other hand, may be used to view tagged species in situ, either biologically or in a chemical process.
