The changes of X-ray diffraction patterns of iron and nitrogen during in situ chemical reaction by XFEL pump-and-probe. An Fe foil surrounded by N2 was pre-compressed to 5 GPa in a DAC. The percentages in run A indicate the transmission (fluence) of the XFEL. At 100% XFEL transmission, run B contains 20 consecutive pulses while run C has consecutive pulses over 11 s.
