dc.description.abstractThe OH stretch mode in rutile (TiO2) has been investigated with polarized Raman scattering. The scattering intensities of the defect ensemble were analysed using an extension of the Raman-Behaviour-Type method to tetragonal host crystals. This allows us to determine the local symmetry of the defect and to clearly exclude specific models, which could not be discriminated so far by IR spectroscopy. The C1h(001) site symmetry detected for the main absorption line is consistent with the sites predicted by potential calculations. The satellite peak interpreted as OH defects associated with Al3+ impurities exhibits a higher symmetry, C2v[001] pointing to a site on the common [110] edges of the oxygen octahedra.
