In summary, we illustrate the intricacies of choosing suitable DFT computational protocol to model the photodynamcis of a transition metal complex. Optimal tuning of a range-separated DFT functional is not a blackbox method and the different nature of the involved states and their mixing make its success unpredictable. Only when combining experimental absorption spectra and photorelaxation timescales, multi-reference calculations and nonadiabatic dynamics simulations, a suitable set of tuning parameters could be found. Fortunately, such all-encompassing endaevors are possible nowadays as time-resolved spectroscopic experiments have become main-stream characterization techniques of transitionmetal complexes and the explicit simulation of their pho-tobehavior with nonadiabatic dynamics methods have become computationally feasible as well.
