Fig. 3: Kinetic traces of selected Bragg peaks in ultrafast X-ray diffraction study.

a Static X-ray diffraction pattern measured at 300 K after scattering background correction. Color circles show the positions of selected Bragg peaks. b Kinetic traces of intensities of selected Bragg peaks from −0.5 to + 6 ps. Solid line show the fitting curves using biexponential decay functions (Supplementary Eq. 2) (c) Kinetic traces of radial positions of selected Bragg peaks from −0.5 to + 6 ps.
