One dimensional hindered rotor model for order-disorder phase transitions in ammonium halide crystals

The hamiltonian for the disordered phase (O h 1 ) of the ammonium halide crystals is derived on the basis of a point charge model which also takes into account the repulsion between nearest neighbour ions (NH 4 + - X - ). This hamiltonian is reduced to that for interacting one dimensional hindered r...
