Abstract: The EPR spectrum of yttrium and scandium silicate single crystals doped with chromium has been studied at various frequencies. Y$_{2}$SiO$_{5}$ has one triclinic Cr$^{3+}$ center, while the Sc$_{2}$SiO$_{5}$ 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.
