摘要：
Two aspects for investigating bipolaronic excitons [charge transfer vibronic exciton (CTVE)] in ionic-covalent solids are considered. These aspects are predictions of the charge-transfer lattice instability corresponding to charge transfer and lattice anharmonicity, as well as to repulsion between different types of CTVEs in the order parameter field. Oxide crystals (SrTiO3, BaTiO3, K3Na(CrO4)2) are considered as an example.
