Abstract
Pulsed electron-electron double resonance techniques have been applied to the ĊH fragment in an irradiated single crystal of malonic acid. Damped Torrey oscillations about the pumping field and also about the observing field have been observed, and the spin-lattice and cross-relaxation times have been measured directly. Display of the transient signal intensity at a constant delay as a function of the pump frequency (i.e., relaxation spectroscopy) yielded very narrow EPR hyperfine lines.Keywords
