Fig. 3. Transient spectra of Λ/Δ-[Ru(TAP)2(dppz)]2+ (400 μM) in the presence of polyd(dG-dC); (a and b) ps-TrA spectra at −100 ps (green), 20 ps (red) and 2500 ps (blue). Inset: exponential growth kinetics for reduced complex at 515 nm; (c and d) ns-TrA spectra at selected delays 0.5–100 ns (black). Inset: monoexponential fit to decay of reduced species at 515 nm; (e and f) ps-TRIR spectra at −100 ps (green), 20 ps (red), 2000 ps (blue), FTIR (black). λexc (psTrA/TRIR) = 400 nm, (nsTrA) = 355 nm. Pump energy = 1 μJ. In aerated 50 mM phosphate-buffered D2O pH 7; Nucl/Ru = 25.
