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. Presented in this paper is the demonstration of rapid scan (RS) EPR imaging implemented at 800 MHz. Generation of stable magnetic scan waveforms is critical for the RS method. A digital automatic ...Rapid Scan-EPR is a revolutionary technique that can improve the signal to noise ratio and significantly decreases the acquisition time (down to milliseconds). The main advantage of RS-EPR comes from the later onset of signal saturation, allowing higher microwave powers to be used.
