Title: Infrared spectral studies of pre- and post-irradiated Li{sub 0.5(1+x)}Ti{sub x}Al{sub 0.1}Fe{sub 2.4-1.5x}O{sub 4} system

The consequences of 50 MeV Li{sup 3+} ions irradiation on the structural behaviour of polycrystalline samples of spinel ferrite system Li{sub 0.5(1+x)}Ti{sub x}Al{sub 0.1}Fe{sub 2.4-1.5x}O{sub 4} are investigated by using infrared absorption spectroscopy. The IR spectrum showed two main absorption bands ν{sub 1} and ν{sub 2} in the range 400-700 cm{sup −1} arising from tetrahedral and octahedral interstitial sites in the spinel lattice. The shifting and splitting observed in IR frequency bands ν{sub 1} and ν{sub 2} for tetrahedral and octahedral sites under irradiation effect are ascribed to redistribution of cations.
