Left: time-resolved XANES spectra of the reduction of Ce(IV) by isopropanol in three-dimensional (top) and two-dimensional (bottom) representation. In the bottom picture, the Ce(IV) (maximal resonance at 5.738 keV) and Ce(III) (no resonance at 5.738 keV) reference spectra used in the LC-XANES fit are shown as black and dark grey curves, respectively. Ovals highlight the isosbestic points. The gap in the spectra is due to an interruption of the X-ray beam during injection of electrons into the storage ring. Right: time-resolved UV/Vis spectra in three-dimensional (top) and two-dimensional (bottom) representation. |
