Mixed valence compounds have intrigued researchers for over 50 years as model systems for understanding electron transfer. Their electronic properties are due to the presence of multiple indistinguishable charge bearing units that can couple and yield non-integral oxidation states. Furthermore, the presence of multiple identical charge transfer sites in a single molecule produces mixed valence excited states. Our group has explored excited state mixed valence compounds to understand its electronic origins and the resulting optical spectroscopy as interpreted within the framework of the time-dependent theory of spectroscopy. This talk will focus on the studies of three excited state mixed valence systems presenting analyses of their optical spectra, electronic structure, and excited state geometry.
