and Summary.-Analysis of the electron spin resonance (ESR) of a 'y-irradiated single crystal of L-tyrosine-HCl reveals a free radical formed by loss of an H from the hydroxyl group attached to the ring. Principal g values of the radical are g. = 2.0023 A 0.0005, g, = 2.0067 + 0.0005, and g, = 2.0045 ± 0.0005, with gx perpendicular to the plane of the ring and g, along the CO bond to the ring. A...
