  • Proton migration in the acetylene cation is commonly used as a model to study isomerisation dynamics. Here, the authors use X-ray pump-probe experiments to study this process, and show that isomerization occurs significantly faster than expected—within the first 12 femtoseconds following core ionization.

  • Photoexciting molecules provides insights into their different degrees of freedom if the ultrafast electron and nuclei motion can be properly analysed. To this end, McFarland et al.use X-ray pump-probe techniques to show that Auger spectra can unveil information on nuclear relaxation in molecules.

  • Imaging the charge flow in photoexcited molecules would provide key information on photophysical and photochemical processes. Here the authors demonstrate tracking in real time after photoexcitation the change in charge density at a specific site of 2-thiouracil using time-resolved X-ray photoelectron spectroscopy.

  • The photochemical electrocyclic ring-opening of 1,3-cyclohexadiene is a textbook organic chemistry reaction. Now, using ultrafast electron diffraction its reaction pathway has been resolved on the level of atomic distances and on its natural femtosecond timescale. Furthermore, coherent isomerization dynamics of the photoproduct 1,3,5-hexatriene were observed.

  • Many photo-induced processes such as photosynthesis occur in organic molecules, but their femtosecond excited-state dynamics are difficult to track. Here, the authors exploit the element and site selectivity of soft X-ray absorption to sensitively follow the ultrafast ππ*/nπ* electronic relaxation of hetero-organic molecules.

  • Electrocyclic reactions proceed through critical geometries, which are known as pericyclic transition states in thermal reactions and pericyclic minima in photochemical reactions. Here, the authors image the structure of a pericyclic minimum in real time using a combination of ultrafast electron diffraction and ab initio dynamics simulations.
