the radical spectra of mixtures of thymidine 5'-monophosphate ( tmp ) or uridine 5'-monophosphate ( ump ) with adenine 5'-monophosphate ( amp ) after hydrated electron attack , measured from 5 to 3000 microsecond after pulse radiolysis , can only be described in terms of the radical spectra of the nucleotides if an electron transfer is taken into account from the purine radical anion to the pyrimidine , resulting in the formation of a pyrimidine radical anion .
