Abstract

Transient absorption data of [Fe^II(tpy)(CN)₃]⁻ reveals spectroscopic signatures indicative of ³MLCT with a ∼10 ps kinetic component. These data are supported by DFT and TD-DFT calculations, which show that excited state ordering is responsive to the number of cyanide ligands on the complex.
