a Area-normalized Kβ X-ray emission spectroscopy (XES) references from Kjaer et al.20. Singlet ([Fe(2,2’-bipyridine)3]2+, blue), doublet ([Fe(2,2′-bipyridine)3]3+, red), triplet (Fe(II)phthalocyanine, orange), quartet (Fe(III)phthalocyanine chloride, purple), quintet ([Fe(phenanthroline)2(NCS)2], green)-. b Two-dimensional map of cytochrome c Kβ XES difference signal. c Difference spectra at various time delays. d Time-dependence for Kβ X-ray emission energies indicated by dashed vertical lines in c. Error bars reflect the standard deviation of the signal within a range of 7 detector pixels around these energies.
