Fig. 2: Time-resolved pump-multiprobe single-crystal diffraction measurements on 1.
From: LED-pump-X-ray-multiprobe crystallography for sub-second timescales
The five plots show the time dependence of the ES population \(\alpha (t)\) during successively shorter pump-multiprobe sequences where the temperature and excitation time are optimised to engineer similar kinetic behaviour. On each plot, the orange and blue shaded regions mark the excitation and decay parts of the sequence, respectively. The markers show the measured \(\alpha (t)\), each refined from a full single-crystal X-ray data set averaged over the time \({t}_{{{{{{\rm{acq}}}}}}}\) indicated on each plot. The solid lines are fits of the data using numerical simulations with a two-process JMAK model with competing excitation and decay.
