Electronic and structural changes induced by photo-excitation of 2-thiopyridone (2-TP) were investigated with inelastic X-ray scattering (RIXS). S. Eckert, J. Norell et al. describe in their Communication (http://doi.org/10.1002/anie.201700239) that an N site deprotonation RIXS signature of 2-TP, established in synchrotron measurements, was identified on a femtosecond timescale using the free-electron-laser LCLS. Quantum chemical simulations ascribe the signature to N lone-pair orbital formation and confirm that X-ray induced dynamics are decoupled from the optically induced deprotonation.
