McConnell superexchange mechanism

Fig. 10 Orbital description of the McConnell superexchange (through-bond) mechanism applied to a system comprising a donor and an acceptor covalently linked to a pentamethylene chain. The donor and acceptor chromophores each contribute a single tt orbital to the interaction and each C-C bridge bond is assumed to contribute a single a or a MO, depicted as the former type in the figure. T is the interaction matrix element between a chromophore tt MO and the ally lie C-C a MO, and t is the interaction matrix element between two geminal C-C a MOs.
