Abstract Theoretical studies on infrared and Raman-active phonons in the Aurivillius ferroelectric Bi 2 WO 6 were performed. These Raman and infrared phonons were calculated by applying a short-range force constant model using normal coordinates having space group P2 1 ab. The calculations of the zone center phonons have been made with nine stretching, one repulsive and 12 bending force constants. The calculated Raman and infrared wavenumbers are in very good agreement with the experimental… CONTINUE READING
