      abstract     = {A comprehensive insight into ultrafast dynamics of
                      photo-switchable materials is desired for efficient control
                      of material properties through light excitation. Here, we
                      study a polycrystalline spin crossover thin film as a
                      prototypical example and reveal the sequential
                      photo-switching dynamics, from local molecular rearrangement
                      to global lattice deformation. On the earliest femtosecond
                      timescale, the local molecular structural rearrangement
                      occurs within a constant unit-cell volume through a two-step
                      process, involving initial Fe−ligand bond elongation
                      followed by ligand rotation. The highly-oriented structure
                      of the nanocrystalline films and the experimental geometry
                      enables resolving the full anisotropic lattice structural
                      dynamics in and out of the sample plane separately. While
                      both molecular switching and lattice heating influence
                      lattice volume, they exert varying degrees of impact at
                      disparate time scales following photoexcitation. This study
                      highlights the opportunities provided by Mega-electron-volt
                      electron and X-ray free electron laser to advance the
                      understanding of ultrafast dynamics of photo-switchable
                      materials.},
