Abstract:
Steady-state γ-radiolysis of 5 × 10 -4 M pyrimidine and purine 2′-deoxyribonucleosides in aqueous solutions saturated with N 2 , N 2 O and O 2 , respectively, have been carried out in the presence of 0.1 M KBr. The main final degradation products have been isolated and characterised by various spectroscopic measurements including 1 H and 13 C NMR, UV, C.D. and mass spectrometry. The radiation-induced decomposition of thymidine is mostly accounted for by an ionic mechanism involving Br 2 , the decay product of Br 2 -·, as the reactive oxidising specie. On the other hand the degradation of the purine ring of 2′-deoxy-adenosine and 2′-deoxyguanosine may be accounted for by the action of Br 2 -·or Br 3 ·2-
