Two previously unreported Ti<sup>3+</sup> paramagnetic centres have been observed in zircon (zirconium silicate, ZrSiO<sub>4</sub>) and studied by X-band electron paramagnetic resonance at 10 K. The first of these is shown to arise from a Ti<sup>3+</sup> electron-trap centre where Ti substitutes into one of the Si<sup>4+</sup> sites, point group symmetry 2m (D<sub>2d</sub>), of the tetragonal crystal. A full spin-Hamiltonian analysis of the centre is given. The second centre arises from Ti<sup>3+</sup> substituting for Zr<sup>4+</sup> in the lattice and interacting with a 100% spin-I = ½ nucleus, probably <sup>31</sup>P, in a nearby lattice site, thought to be a next-nearest-neighbour Si site. The point group symmetry of the site of this centre is 2 (C<sub>2</sub>). |
