Abstract
A radiofrequency (RF) coil design, suitable for detecting time domain electron paramagnetic resonance (EPR) responses from spin probes after pulsed excitation using radiofrequency irradiation (60-400 MHz), is configured in an array of numerous surface coils of appropriate diameters connected in a parallel or axial configuration with appropriate spacing between individual surface coils to form a volume type resonator.
