dc.description.abstractA short range force constant model has been applied for the first time to investigate the Raman and the infrared frequencies in A2Sn2O7 (A=La, Sm, Yb, Lu) pyrochlores in their cubic phase of space group Fd3m. The calculations of zone center phonons have been made with six stretching and three bending force constants. The calculated values of Raman and infrared frequencies are in good agreement with the observed ones.en
