Paramagnetic resonance of ZnSe: Fe single crystals was studied at 120 K. Parameters of the spin Hamiltonian were determined for the monoclinic dimer complex Fe^3+–Cu^+ and a second discovered Fe^3+ center, which appears due to association of the iron ion with a K^+ ion in a Zn^2+ position or with a zinc vacancy. Effect of illumination of the zinc selenide samples by blue, green and red light on the paramagnetic resonance spectrum was investigated.
