Pump–probe spectroscopy of 1a in 87% aqueous CH3CN. The sample was excited with a pulse from a Ti/Sa–NOPA laser system (266 nm, 150 fs pulse width, pulse energy 1 μJ).10 The inset shows the species spectra of T1 and 33 that were determined by global analysis of the spectra taken with delays of 10–1800 ps using a biexponential fit.
