As shown above, the selection of the range-separation parameters has a significant effect on the nature of the lowest excited states for the Franck-Condon geometry (Figure ) and on the PESs of the breathing mode of [Fe(cpmp) 2 ] 2+ (Figure ). How much this affects the photodynamics of the complex will be investigated using TSH nonadiabatic simulations on linear vibronic coupling (LVC) parametrized potentials along the 213 vibrational degrees of freedom of [Fe(cpmp) 2 ] 2+ . The LVC models were setup for the range-separation parameters of set A and set B including 11 singlet/20 triplet states and 9 singlet/14 triplet states, respectively, corresponding to the number of electronic states in the energy range of the lowest-energy absorption band (up to 2.5 eV, Figure ). Full computational details are reported in Section The resulting TSH dynamics in the LVC electronic potentials from both sets of range-separation parameters are shown in Figure for the first 500 fs. We performed SH dynamics for a total of 2 ps (Figure
