Researchers in California have used an X-ray scattering method to monitor step-by-step femtosecond structural rearrangements of a molecule undergoing a ring-opening reaction (Phys. Rev. Lett. 2015, DOI: 10.1103/physrevlett.114.255501). The study describes a new ultrafast pump-probe method that deepens understanding of chemical reaction dynamics and lays the groundwork for recording X-ray movies of chemical reactions in real time. To trigger the reaction, Michael P. Minitti of SLAC National Accelerator Laboratory . . .
