On the radiation chemistry of some pyrimidine-electron adducts: reaction of pyrimidine negative ions with t-butanol radicals.
The rates of decay of the electron adducts of thymine, thymidylic acid and of uracil at pH approximately 8-5 and at wave-lengths of 340 or 350 nm in the presence of t-butanol as scavenger for OH radicals are not influenced significantly by the addition of 0-1 M NaClO4. It follows that the decay reactions do not take place between negatively-charged species. The best explanation seems to be an efficient reaction of the electron adducts with the t-butanol radicals formed by reaction of OH radicals with the t-butanol.
