Figure 1: Nitrogen K-edge X-ray absorption spectra of (a) oxyMb, (b) deoxyMb, and (c) metMb in aqueous solutions at 25 °C within the energy regions of the porphyrin C=N π* peaks. The spin states of heme irons were studied from the inner-shell calculations using the molecular structures shown in the figure.
