Popis:	Radiation-induced radicals in a single crystal of dihydrothymine were studied with EPR. It was found that the 5-thymyl radical is the dominant radical species at room temperature. The orientation dependence of the hyperfine couplings can only by explained if one assumes that C(5), C(6) and C(7) lie in the plane defined by the rest of the nonhydrogen atoms of the ring. The highly dis-ordered structure of the ring in the undamaged crystal is ordered if a proton bound to C(5) is removed.
