Photoinduced spin-switching in molecular complexes containing d4-d6 transition metal ions is an important phenomenon that enables numerous applications in chemistry, biology and nanotechnology. At the microscopic level, this process originates from the bistability between a low-spin (LS) and a high-spin (HS) state, which can be activated through light irradiation. Although the vast majority of...

The fate of a photoactive molecule is determined by the electronic and structural rearrangements that follow excitation. Femtosecond (fs) X-ray free electron lasers (XFELs) have made it possible to use X-ray absorption spectroscopy to probe changes in electronic configuration and atomic structure as a function of time, beginning from the initial excited state. Both ‘movies’ of coherent or...
