dc.description.abstract	The phonons of two end members of Li1+xTi2−xO4 spinel system, i.e., the metallic LiTi2O4 and the insulating Li[Li1/3Ti5/3]O4, are calculated in superspace symmetry approach using a short-range force constant model. The composition dependence of zone-centre optical phonons in Li1+xTi2−xO4 near phase transition and Li1−xMgxTi2O4 has been investigated using different models of substitution.One-andtwo-mode behavior is therefore predicted for F1u and F2u modes in case of tetrahedral and octahedral substitution, respectively.	en_US
