A soft touch : Interconversion of two redox isomers of a cobalt dioxolene complex (see picture; Cat: catecholato, SQ: semiquinonato) is stimulated by soft X‐rays. Analysis of X‐ray absorption spectroscopy (XAS) spectra shows that the soft‐X‐ray‐induced redox isomer is the same as that obtained by optical irradiation of the sample in the near‐IR region or by warming the sample.
