“…13,75 In this method, short x-ray pulses of 100-150 ps duration emitted by the synchrotron and ultrashort pulses generated by femtosecond lasers are combined to obtain direct structural information that is difficult to extract using ultrafast optical spectroscopy alone. 76 In some TRXL experiments, instead of monochromatic x-ray pulses, polychromatic pulses are used to increase the signal-to-noise ratio.…”

Ultrafast time resolved x-ray absorption and x-ray diffraction have made it possible to measure, in real time, transient phenomena structures and processes induced by optical femtosecond pulses. To illustrate the power of these experimental methods, we present several representative examples from the literature. (I) Time resolved measurements of photon/electron coupling, electron/phonon interaction, pressure wave formation, melting and recrystallization by means of time resolved x-ray diffraction. (II) Ultrafast x-ray absorption, EXAFS, for the direct measurement of the structures and their kinetics, evolved during electron transfer within molecules in liquid phase. (III) XANES experiments that measure directly pathway for the population of high spin states and the study of the operating mechanism of dye activated TiO2 solar cell devices. The construction and use of novel polycapillary x-ray lenses that focus and collimate hard x-rays efficiently are described.
