Some properties of excitons in polar crystals are studied. The effective Hamiltonian of the exciton in polar crystals is derived by a perturbation method. If we consider the interaxtion between phonons of different wave vectors in the recoil process, the influence on the effective potential between electron and hole, the self‐trapping energy, and the self‐trapping condition are discussed.
