Abstract
The solvent dependence of the radiative-rate constant of both inter- a nd intramolecular donor-acceptor systems reveals the occurrence of sig nificant intensity borrowing from one or more local transitions. This phenomenon appears to be especially pronounced in systems of the type D-3 sigma-A, where donor and acceptor interact via through-bond intera ction over a relay of three sigma bonds. Within the context of a three -state model, involving the no-bond state (DA), the charge transfer st ate (D(+)A(-)) and a single locally excited state [(DA)], a simplifie d method is given to analyse the electronic coupling elements between these states.
