Fig. 3: Kβ XES spectra of MbNO at various time delays after visible photoexcitation.
From: Femtosecond X-ray emission study of the spin cross-over dynamics in haem proteins
Laser-off (−0.09 ps) and Laser-on Kβ XES spectra of MbNO at different time delays between 0.026 and 1.36 ps (from blue to red) showing a blue shift of the Kβ1,3 line and an intensity decrease. The inset zooms into the region of the maximum of \(K_{\beta _{1,3}}{\mathrm{{XES}}}\) line at different time delays between −0.09 and 1.36 ps (from blue to red) showing peak shifts smaller than the energy resolution (~0.5 eV) of our experiment.
