Measurements of spin-lattice relaxation times in potassium chromicyanide diluted with potassium cobalticyanide have been made on crystals of nominal concentration of chromium varying from 5% to 0.1%. Crystals were grown in the laboratory and studied using saturation method. The relaxation times were measured for forbidden transitions at 9.4 KMc/s which occur at low magnetic fields. Spin-lattice relaxation times are of the same order of magnitude as for allowed lines. Spin-spin interaction time increases with decreasing concentration for the range of the concentration used. All measurements were made at a constant temperature of 4.2° K.
