The energy of partially ionic states in charge-transfer crystals is calculated in a simplified model allowing the molecular polarizabilities to depend on the degree of charge transfer. This extra feature allows an energy minimum for fractional charge transfer in favourable cases.
For charge-transfer excitons strongly interacting with vibrations of a donor-acceptor chain, soliton-like states are found to have an internal structure: at a certain ratio of polaronic shift and electron-hole relative motion energy, a transition from a symmetric to a dimerized soliton occurs accomp
