a Experimental Kβ X-ray emission difference signal. b Best fit using a model with a triplet intermediate state. c Fit residual. d Resulting time-dependent populations for the 1π−π*, 3MC and 5MC states and the ground state (1GS). The 1π−π* and 5MC lifetimes were fixed to 145 fs and 5.9 ps, respectively. Fitted time constants are 118 ± 61 fs for the instrument response function FWHM and 87 ± 51 fs for the 3MC lifetime.
