Abstract (english)

ESR spin-trapping method has been used for the study of
radiation-induced radicals in· powdered dihydrothymine. Four approximately
equal small proton couplings (AH' = 0.35 mT), a larger
proton coupling (AH = 0.195 mT) and a nitrogen coupling (AN =
= 0.295 mT) are attributed to the nitroxide radical formed by
reaction of the spin trap with 6-dihydrothymyl radical upon dissolving
of dihydrothymine. In the pyrimidine bases of nucleic acid
and a number of related compounds irradiated in solid state and
dissolved, no signs of the trapped radicals were observed.
