Abstract
Superheterodyne detection using a crossed-loop resonator permits obser vation of species with long electron-spin-relaxation times without pas sage effects and permits observation of dispersion spectra with higher signal-to-noise than absorption spectra. This was demonstrated with S -band (2.9 GHz) absorption and dispersion spectra for the defect cente rs in gamma-irradiated fused SiO2 and for the radicals in coal. (C) 19 96 Academic Press, Inc.
