Fig. 5. X-ray absorption near-edge structure (XANES) spectra and modeled fits with Mn(II) from the repeated-scan studies. The spectra shown are the first and last in each series. Dotted lines show the model fit to the first scan and the combination of this model with Mn(II) that best fits the last scan. A spectra of aqueous Mn(II) is given in (a) for comparison
