ESR spectra of I /sup 17/O/sub 2/ embedded in solid KC10/sub 4/ exhibit a complicated /sup 17/O hyperfine structure, which allows an accurate determination of the hyperfine and quadrupole tensors A(/sup 17/O) and Q(/sup 17/O). A(/sup 17/O) is strongly anisotropic in the molecular plane and contains an asymmetric component. These unexpected features are accounted for in terms of second-order contributions to A(/sup 17/O) arising from cross terms of the spin--orbit coupling and the orbital and spin dipole hyperfine interaction. The second-order terms also contribute substantially to the hyperfine tensor of the iodine nucleus.
