Abstract The cover picture shows a Class II/III mixed‐valence system, {[Ru 3 O(OAc) 6 (CO)(pyridine)] 2 –pyrazine} –1 , which undergoes picosecond intramolecular electron transfer (right). In nearly delocalized mixed‐valence complexes, rates of ET depend highly on solvent dynamics. Freezing of the solution causes a localized‐to‐delocalized transition, and rates of ET increase. We find that, for Class II/III mixed‐valence complexes, solvent dynamical parameters control rates of ET and tend to localize otherwise delocalized electronic states. Details are presented in the Microreview by C. P. Kubiak et al. on p. 585 ff.
