We have computed the x-ray absorption spectrum for the Ti K-edge in rutile titanium dioxide (TiO 2 ) in the frame of the multiple scattering approach, varying the atom positions within the coordination sphere. This allowed us to understand the origin of the absorption structure variation. The analysis has been achieved by making distortions of the axial and equatorial Ti-O distances or of the O eq -Ti-O eq equatorial angle along the c axis. Computations are performed using FEFF (version 6) code for TiO 2 with Dirac-Hara and Hedin-Lundqvist exchange potentials. From the results, we can better understand why the amplitude of one or several structures is modified referring to TiO 2 , when a variation of the local geometry occurs. † Current address:

“…Amongst the rutile family, the best known is titanium dioxide (TiO 2 ), because of its large industrial interest [1]. It is used in white pigment production in the paintwork domain (the most important), but also in paper, ceramic, textile or glass manufacture [2,3] and also catalysis [4].…”
