Figure 5
HERFD (orange) and TFY-XAS (blue) spectra for both (a) (PPh4)2WS4 and (b) Na2S2O3. TFY-XAS spectra are collected in fluorescence mode on a thin sample and HERFD spectra are a diagonal cut of the RIXS plane. In both cases, the HERFD spectrum shows modest improvement in the energy resolution with respect to the TFY-XAS spectrum. |
