electron spin resonance
- a technique for investigating paramagnetic substances by subjecting them to high-frequency radiation in a strong magnetic field. Changes in the spin of unpaired electrons cause radiation to be absorbed at certain frequenciesAbbreviation: ESR See also nuclear magnetic resonance
