Single crystals of PbMoO4 were studied by means of light-induced EPR and wavelength resolved TSL. The work is focused on the electron self-trapped at the (MoO4)2- complex. Detailed analysis of the EPR spectra of this complex allowed to determine a set of spin-Hamiltonian parameters further used in calculations performed in terms of crystal field and LCAO-MO theories. They have shown a significant overlap of the Mo ligand lead orbitals. Trap depth and frequency factor of the electron trap, Et = 0.05 eV, and f0 = 104 s−1, have been determined in correlation with TSL.
