    We present a real-time path integral theory for the rate of electron transfer reactions. Using graph theoretic techniques, the dynamics is expressed in a formally exact way as a set of integral equations. With a simple approximation for the self-energy, the rate can then be computed analytically...

    The morphology of the dynamic electron transfer characteristic of chemical reaction dynamics has been studied by introducing the new criterion of an isomorphism of the manifold of electron orbitals at the different points of the reaction coordinate. This criterion is a natural development of the...
