noun

  1. physics another name for electron spin resonance Abbreviation: EPR

noun

  1. 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

n.

  1. A spectrometric method, based on measurement of the spins of unpaired electrons in a magnetic field, for detecting and estimating free radicals in organic reactions.
