In this paper we report the experimental angular behaviour of the EPR spectra for a single crystal of Thorium disulfide (ThS 2 ) doped with Gd 3+  at very low concentration (of the order of 10 p.p.m.). The experimental data are interpreted in terms of a spin Hamiltonian which reflects the crystal field symmetry at the Th site, that is monoclinic C s , and therefore shows that the doping ions enter substitutionally without lowering the site symmetry. The low symmetry and the unusually large values of the crystal field parameters b 2  0  and b 2  2  have made it necessary to use a numerical fitting procedure, starting from the exact numerical diagonalization of the energy matrix for any given direction of the static magnetic field.
