Fe and Mn L3-edge soft X-ray absorption spectroscopy (sXAS) spectra collected on a series electrode samples of NaxMnFe(CN)6·zH2O systems, (A) Fe for hydrated, (B) Fe for anhydrated, (C) Mn for hydrated, and (D) Mn for anhydrated. The calculated values were achieved by linear fitting of reference spectra. Reprinted from Wu et al. (2017) with no permission required from authors.
