Free-radical formation was studied in x-irradiated single crystals of histidine HCl using conventional electron spin resonance (ESR) as well as double-resonance (ENDOR) spectroscopy. The spectra are attributed to a free radical formed by the addition of hydrogen to the C2 position on the imidazole ring of histidine.
