Abstract
We consider a simple model which contains both electron phonon coupling, electron transfer, and electron correlation, which can be a prototype of a mixed valence system with three nearby electronic states. We treat the adiabatic solution, simple corrections to that, and the effect of symmetry breaking terms on the solutions. We find that the adiabatic solutions in the symmetric case can show a (false) symmetry breaking which is removed in the nonadiabatic calculation. These solutions are extremely unstable with respect to the addition of a non-symmetric term in the Hamiltonian.
