X-ray free-electron lasers provide intense, short-pulse, short-wavelength radiation that can be used to study ultrafast electronic and structural dynamics in gas-phase molecules with unprecedented spatial and temporal resolution. I will present recent examples of experiments utilizing a variety of different techniques such as time-resolved photoelectron spectroscopy [1] and Coulomb explosion imaging [2,3]. The results are compared to similar experiments performed with other ultrafast techniques such as ultrafast electron diffraction and strong-field ionization based experiments with near-infrared laser sources [4] in order to highlight strengths and limitations of each technique.
