Figure 3
ED-XANES data clearly exhibiting a continuous overall positive shift in energy with irradiation time ranging from 1 to 100 s, measured from a 0.69 M Fe(II)Cl2 aqueous solution sample at 573 K. The inset shows a Lorentzian peak (thick smooth line) fitted to the derivative of the ED-XANES (thin irregular line) measured at 1 s that is used to determine the location of the Fe K-edge. |
