Other AbstractUsing the ns pulse radolysis; we studied the characteristic absorption spectrum and kinetic decay of cytosine anion radical (Cyt). Reslults showed that the characteristic absorption of Cyt' was located at λ=355±5 nm; and decayed following the first order kinetics with T1/2=265 ns at pH=7.0. The decay;became slower and T1/2 rapidly rised with the increment of pH value; Cyt'protonated at C6 in acidic solution; and the characteristic absorption was located at λ=310±5 nm;and decayed following the second order kinetics: Cyt' protonated at N3 in aqueous solution of pH≥7; and the characteristic absorption was located at λ=295±5 nm; and decayed following the second order kinetics.
