Laser Flash Photolysis and Pump-Probe Spectroscopy

2 Laser Flash Photolysis and Pump-Probe Spectroscopy 

The A4 amplitude corresponds to Ti state, invariant since its lifetime is much longer than the timescale femtosecond experiment. Adequate mathematical treatment leads to the full assignment of the transient spectra and of the rate of conversion, so that the complete state diagram is reconstmcted (see Fig. 6.9). 

9 Nanosecond las flash photolysis (see Fig. 6.7) and femtosecond pump-probe experiments (see Fig. 6.8) allow to determine the spectra and the reaction rate of diiodoBODIPY (10) excited states and their reaction with oxygen. Reprinted with permission from [24] 

3 M acetate buffer, pH = 3.6 1 ns after the laser pulse with 3 ns accumulation time). The dashed gray spectra (their intensity was reduced by a factor of 2.5) correspond to the triplet states of the reagent 14 top, n= 1 bottom, n = 3). Reprinted with permission from [25]
