(a) In a pump–probe experiment, a single X-ray probe pulse is timed to measure the excited state population at a specific time delay Δt after excitation by the pump light source. The complete experiment is repeated for each Δt to be measured. (b) In the pump–multiprobe method, a series of probe pulses are generated after each pulse to measure multiple time delays in a single experiment. [Reproduced from Hatcher et al.
