Fig. 6. TA results for SPh. (a) TA spectra of SPh probed at indicated time delays following 350 nm excitation. The SE and ESA features of SPh are indicated. (b) Normalized FU kinetics (green triangles) and TA kinetics of SPh probed at SE (blue squares) and ESA (red circles) peaks. The FU kinetics of SPh⊃C₆₀ is also shown with wine triangles. (c) TA spectra of SPh⊃C₆₀ probed at indicated time delays following 350 nm excitation. The absorptions of SPh+, , and C₆₀⁻ are also indicated. (d) Normalized TA kinetics of SPh⊃C₆₀ probed at the (red squares), SPh+ (blue circles), and C₆₀⁻ (green triangles, the black line shows the fit).
