The far-infrared (FIR) Laser Magnetic Resonance (LMR) spectrum of the 17OH radical in the v = 0 level of the X2Π state has been studied in detail. The measurements have been analyzed and, in combination with some earlier EPR measurements, subjected to a single least-squares fit using an effective Hamiltonian. A full set of 17O nuclear hyperfine parameters has been determined. Some implications of these parameter values for the electronic wavefunction of OH are considered.
