ESR--ENDOR measurements were made on single crystals of 5-nitro-6-methyluracil x-irradiated at 4.2 K. The primary oxidation and reduction products were characterized and identified. The reduced species has a large spin density localized on the nitrogen atom of the nitro group. The hyperfine and quadrupole coupling tensors of the /sup 14/N nucleus were determined from ENDOR measurements. The oxidized species is the cation formed by removal of an electron from the uracil ring. (AIP)
