Figure 5.
Transient absorption spectra recorded in deoxygenated and buffered with phosphate (10 mM, pH = 7.0) BrSdU solution (5 · 10−5 M), in the presence of 0.5 M t-BuOH (A) after 12 μs (■) and 120 μs (◯) and (B) (■) 12 μs after the electron pulse. (C) Short-time profiles representing the growth at λ = 300 nm (◯) and the decay at λ = 720 nm (■) of transient absorptions and their least-square fits to the first order formation and decay, respectively. (D) Long-time profiles representing the growth at λ = 335 nm (■) and decays at λ = 300 nm (◯) of transient absorptions and their least-square fits to the second order formation and decays, respectively.
