electron spin resonance (ESR)or electron paramagnetic resonance (EPR)Technique of spectroscopic analysis (see spectroscopy) used to identify paramagnetic substances (see paramagnetism) and investigate the nature of the bonding within molecules by identifying unpaired electrons and their interaction with their immediate surroundings. Unpaired electrons, because of their spin, behave like tiny magnets and can be lined up in an applied magnetic field; energy applied by alternating microwave radiation is absorbed when its frequency coincides with that of precession of the electron magnets in the sample. The graph or spectrum of radiation absorbed as the field changes gives information valuable in chemistry, biology, and medicine. ESR (physics)

These medical and health titles are recommended for teen audiences, as well as many an adult or ESR students who will find them equally important. The ESR calibration is traceable to the High Accuracy Cryogenic Radiometer (HACR), the U. Galloo then puts the rest of the plastics through a series of four modified ESR dense-media separation drums containing liquids of different densities (1. |
