electron paramagnetic resonance

[i′lek‚trän ¦par·ə·mag¦ned·ik ′rez·ən·əns]
(physics)
Magnetic resonance arising from the magnetic moment of unpaired electrons in a paramagnetic substance or in a paramagnetic center in a diamagnetic substance. Abbreviated EPR. Also known as electron spin resonance (ESR); paramagnetic resonance.
