A central part in understanding the light-induced properties of the potential photocatalyst prbimRuPt is the characterization of the electronically excited states and their dynamics. The Franck-Condon region based on UVvis absorption and resonance Raman (rR) spectra is subject to discussion as well as the excited state dynamics upon photoexcitation at 400 nm. The discussion covers the corresponding data of both the heterodinuclear complex (prbimRuPt) and its mononuclear counterpart (prbimRu) to fully comprehend the impact of the Pt-center on these properties. The data is supported by time-dependent density functional theory (TD-DFT) results obtained for the optimized singlet and triplet geometries of prbimRuPt and prbimRu, respectively.
