Description
With the implementation of the European x-ray free electron laser a unique tool for time-resolved studies of small molecules and clusters emerges. The targeted pulse durations and photon energies will enable investigations which, firstly, involve more tightly bound K-shell electrons of common small molecules as N2, CO or hydrocarbons, secondly, address typical timescales of molecular decay process in the low fs-regime. By means of coincidence detections techniques as, for example, Cold Target Recoil Ion Momentum Spectroscopy (COLTRIMS) it was demonstrated in the past, that in a few special cases, the molecular time domain is already accessible in measurements using synchrotron radiation. The talk will present two examples of such time-resolved coincidence measurements investigating the temporal evolution of an electron orbital during the dissociation of a small molecule and the electronic decay of carbon monoxide molecules. The final part of the talk will point out future prospects of the combination of coincidence measurements and the unique properties of the light generated at the European XFEL.
