Potassium dichromate single crystals were synthesized from aqueous solution by isothermal evaporation of the solvent. The electron paramagnetic resonance (EPR) spectra were studied from Cr 5+ ions, stabilized by 60 min heating of X‐irradiated crystals at 120°C. EPR spectrum was observed which consists of a strong central line and four almost equidistant satellites with intensities as weak as 2% from that of the central one. The received EPR spectrum may be described within the experimental errors by the anisotropic spin Hamiltonian, the constants at 77°K being: g ∥ = 1.982 ± 0.001, g ⊥ = 1.925 ± 0.001, A ⊥ = 10.2 ± 0.4 G and A ⊥ = 4.0 ± 0.4 G.
