Forster mechanism chromophore electronic coupling

In the first contribution, Huxter Scholes present a review of the recent evolution of theory of EET in condensed phase from their earliest and simple formulation, based on the Forster theory to the most recent advances of theoretical and computational methods based on continuum solvation models. In the second contribution, Curutchet reviews the recent developments of PCM towards accurate theoretical investigations of EET in solution. In particular, the modelization of the various contributions of solvent effects in the chromophore-chromophore electronic coupling is presented using quantum-mechanical approaches. 

There is another context in which long-range overlap independent interactions are important, namely, dipole-dipole (or Fdrster ) coupling between dipole-allowed electronically excited states of chromophores. Since the Forster contribution to the coupling has a power law (R ) distance dependence, and, as will be shown below, the TB and TS interactions fall off exponentially with increasing distance, the Forster mechanism dominates, except for systems with short bridges. For the corresponding triplet states there is no counterpart to the Forster mechanism, and TB and TS interactions dominate.
