Description
After X irradiation of thymidine single crystals at 10 K, three base-centered free radicals were trapped and detected by ESR/ENDOR/FSE spectroscopy. One of these was the thymine anion. The data shows that the anion has an extra proton attached to the O4 position; thus the radical is apparently in a neutral charge state. The coupling to the methyl group is small, less than 3 MHz. Upon thermal annealing the anion decayed at about 40 K evidently into a diamagnetic product since no successor was detectible.
