All Xcited : At low temperatures, an intense beam of hard X‐rays excites photoswitchable molecular spin‐crossover systems to generate metastable high‐spin states (see picture). These states have spectroscopic properties similar to those of the states generated by light‐induced excited‐spin‐state trapping. The new approach offers an excitation source with greater penetration.
