Electron spin resonance



Electron spin resonance (ESR), sometimes called electron paramagnetic resonance (EPR), is a technique for studying the structure and properties of species containing unpaired electrons. Thus it is restricted to free radicals, paramagnetic metal ions and molecules in a triplet electronic state. The technique involves the absorption of microwave radiation, which induces transitions between electronic magnetic energy levels.
