N2 - The formation of two independent paramagnetic centres Ru(JT) and Ru(A) was detected by the EPR method LiH and LiD single crystals doped with ruthenium, after illumination with visible light at T=77 K. Both centres were assigned to Ru+ with low-spin 4d7 configuration. Ru(JT) centres exhibit a quasidynamical Jahn-Teller effect. The values of tunnelling splitting 3 Gamma and random-strain splitting delta were estimated to be 24 cm -1 and 6.0 cm-1, respectively. The Ru(A) centre was found to have tetragonal symmetry with the unpaired electron in a 4d(3z 2-r2) orbital.
