The investigation of the Raman and Infrared wavenumbers has been made in tetragonal structure of the complex Sr2TiO4. This is a member of the Ruddlesden-Popper series Srn+1TinO3n+1 with n=1. Five stretching and four bending force constants were used for the calculation of zone center phonons in this paper by applying a short range force constant model, using normal coordinates having space group I4/mmm and symmetry D4h17. The Calculated frequencies have been assigned 4h and are in a very good agreement with the experimental frequencies in the literature. The contribution from each force constant towards the Raman and infrared wave numbers has also been determined with the investigation of the potential energy distribution.
