• The optical spectrum due to the exchange coupled Cr^<3+> ions in ruby has been studied theoretically. The effect of the lowering of the Cr^<3+> site symmetry due to the formation of a pair was taken into account. For the 2nd neighbor pair, a good fitting of the excited state energies between theory and experiment was obtained. The effect of the higher order exchange is found to be very important for this pair. It is also found that the deviation of the Cr^<3+> site symmetry from C_3 is rather large for this pair. For the 4th neighbor pair, the level diagram of the excited state was obtained and the absorption intensities were calculated. Most of the observed lines in this pair are explained by this theory. The lines so called N_1 and N_2 are found to be the transitions due to the exchange induced electric dipole.
