Figure 5
Time-dependent photo-induced Fe difference spectra (b) and kinetic modelling of spin crossover dynamics [(a) and (c)] for Fe(bpy)3. After excitation into the metal–ligand charge transfer state, transition into the HS 5T2 state [inset in (c)] causes an increase of the Fe-to-ligand distance [inset in (a)]. The difference signal measured at a fluorescence energy of 7061 eV [(a) green diamonds] and 7054 eV [(c) black symbols]. The data have been overlaid with results from global fits including (blue lines) and excluding (green dashed lines) population of and intermediate 3T2 triplet state. Courtesy of Zhang et al. (2014). |
