The model is constructed as a two-level electronic monomers with ground and excited electronic states, |g⟩ and |e⟩ with a fundamental transition frequency of ωeg . Each electronic level has a set of N vibrational states with vibrational frequency, ω0 . As described below these are produced by canonically transforming the single vibrational mode into the environment ensemble of phonon modes . The harmonic potentials for the electronic states result in a monomer system Hamiltonian:
