a, The background density map corresponds to the conventional ΔPDF derived from measured ΔsM, while the positions of the sparse pair distributions reconstructed through Δs-PDF are marked as scatter points overlaid on the ΔPDF. The error bars are estimated via bootstrap resampling and represent one standard deviation. The closest (R1), second nearest-neighbor (R2), and diagonal (R3) C-C interatomic distances for the steady-state structure are given at the bottom. The wave packet bifurcates at approximately 100 fs and the subsequent evolution in the ring-opening and ring-closing pathways are indicated by the arrows. The center of the enhanced bands for HT is determined with super-resolution analysis. b, c Simulated ΔPDF of ring-closing and ring-opening trajectories, respectively. The simulated results are convolved with a Gaussian function with 80-fs FWHM. Source data are provided as a Source Data file.
