Data are presented on the second order Raman spectrum of rutile TiO 2 for various scattering geometries, at room and liquid N 2 temperatures. The results of a standard critical point analysis (i) allow the most important addition processes at low energies to be identified, (ii) indicate the importance of matrix element effects, and (iii) cannot account for a peak at 172 cm −1 for the Y ( xy ) X geometry.
