• EPR in E^^-(^2E) of Cr^<3+> in Al_2O_3 for H⊥c_3 (θ=90°) is investigated by an optical detection and ∣g_⊥∣ is precisely determined to be 0.0515±0.0001, which agrees fairly well with the calculated value of 0.061. The signal intensity as well as the line width varies in complicated manners depending on θ near 90°. Mechanisms of the optical detection are discussed and it is shown that the observed signals at θ=90° can be attributed to the spins whose c_3-axes are misaligned by random strains. The θ dependence of EPR signals is also explained by assuming the presence of misaligned spins. A pair of dips was observed in the EPR line and is interpreted as the results of the cross relaxation due to one spin flip in E^^-(^2E) accompanied by the flip of two spins in ^4A_2.
