While the surface slabs created differ greatly in size and complexity, some general trends in relaxations were observed regardless. Displacements of atoms greater than 0.2 Å were contained within the topmost two layers in all slabs. Many surfaces were cleaved so that two Ti-O eq (equatorial O) bonds were cut and the Ti was left decreased by less than 5°in all slabs, while the second subsurface angle is close to 180°.
