The EPR spectrum of yttrium and scandium silicate single crystals doped with chromium has been studied at various frequencies. Y₂SiO₅ has one triclinic Cr³⁺ center, while the Sc₂SiO₅ crystals demonstrate two nonequivalent centers. The spin Hamiltonian parameters of these centers have been determined. These centers are found to be tricharged chromium ions localized in the yttrium and scandium positions.
