The paper acknowledges this company for XAFS measurements and analysis. Panels a and b are C/N soft XAS and were not measured with this instrument. Mn K-edge spectra appear in c and e–g.

Figure 2: source research figure — Figure 2. Electronic structure and local coordination environment. (a, b) C and N K-edge sXAS spectra for Mn-CN and Mn-CNO. (c) Mn K-edge XANES spectra with reference standards (Mn foil, MnO, Mn2O3, MnPc, MnO2). (d) Mn oxidation states determined from XANES edge positions. (e) Fourier-transformed EXAFS spectra. (f) EXAFS fitting curves for Mn-CNO in R-space. (g) Wavelet transform plots.

Source figures may contain other techniques and soft X-ray spectra. C, N and O measurements are outside our current hard-XAFS testing range.
