Singlet state (S1) radiative and non-radiative decay rates and S1 polarisabilities have been determined for naphthalene dimers where the chromophores are separated by a rigid polynorbornane bridge of varying length corresponding to 2, 4 and 6 σ-bonds. The dramatic increase in S1 radiative rates and polarisabilities as interchromophore separation is reduced is attributed to the contribution of a 'through-configuration' interaction (involving interchromophore charge-transfer states) to the electronic coupling.
