In rapid-scan EPR the signal is detected directly, and unlike conventional slow-scan CW EPR, magnetic field modulation and phase-sensitive detection at the modulation frequency are not used. Instead, the magnetic field is scanned through the EPR resonance many times per second, and the absorption and dispersion signals are recorded. ...ArmyAbstract. In rapid-scan EPR, the magnetic field is scanned through resonance in a time that is short relative to relaxation times. The signal is recorded with a quadrature mixer at the resonance frequency.

Electron paramagnetic resonance. Electron paramagnetic resonance ( EPR) or electron spin resonance ( ESR) spectroscopy is a method for studying materials that have unpaired electrons. The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but the spins excited are those of the electrons instead of the atomic nuclei.
