Zone-centre Raman and infrared phonon frequencies for the spinel phases of oxides Li_{1+x}Ti_{2-x}O_4 (x=0.33) and Li_{1-y}Mg_{y}Ti_2O_4 (y=0.1, 0.3) of space group Fd3m have been calculated using a proposed short-range force constant model. In this model, the lattice potential energy is expanded using Taylor's expansion in the harmonic approximation. The calculated zone-centre phonon frequencies are in good agreement with the available experimental and previously calculated results.
