Resonators for Clinical Electron Paramagnetic Resonance (EPR)

, 2020
In pulsed electron paramagnetic resonance (EPR), free-induction decay (FID) or spin echo (SE) signals of unpaired electrons are recorded in the time-domain. In both methods, electromagnetic waves play an important role in the detection of unpaired electrons in EPR spectroscopy.
