ELECTRON SPIN RESONANCE (ESR) SPECTROSCOPY

Electron 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 ...

useful information using the technique of electron paramagnetic resonance (EPR) spectroscopy. 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.

Nuclear magnetic resonance The general principles exemplified by paramagnetic resonance underpin methodology of Nuclear magnetic resonance (NMR). NMR principally used to determine structure of molecules in chemistry and biology, and for studying condensed matter in solid or liquid state. Method relies on nuclear magnetic moment of atomic nucleus,
