Figure 3
Observed M2,3-edge RIXS (energy difference spectra) of NiO, excited at 66 (a, orange), 68 (b, green), 70 eV (c, blue); and of NiF2 (d, red), [Ni(II)(tfd)2]= (e, black), [Ni(III)(tfd)2]− (f, purple) at 70 eV. The black curve at the bottom illustrates the elastic peak position (×0.01). The vertical bars correspond to the possible d–d transition peaks. |
