摘要：

Based on density functional perturbation theory, we have studied the vibrational properties of crystalline Li2TeO3. The calculated Raman and IR spectra are in good agreement with available experimental data and allow assigning the experimental peaks to specific phononic modes. (c) 2007 Elsevier Ltd.
