The molecular beam electric resonance method was employed to obtain a complete set of hyperfine Λ doubling transitions of the free radicals OH, OD, SH, and SD. The observed spectra could be explained very well by the degenerate perturbation theory adapted to the 2Π state. The experimental results include fine and hyperfine coupling constants, the electric dipole moments could be explained very well by the degenerate perturbation theory adapted to the 2Π state. The constants agree well with ab initio calculations.

Theoretical Results

Dipole moments are measured for OH (2Π) in the ν = 0, 1, and 2 vibrational states and for OD in the ν = 0 and 1 states using the molecular beam electric resonance technique. These are listed in the table below.[Formula: see text]A very accurate value of 0.00735(7) D is obtained for the difference in dipole moments between the ν = 0 and 1 vibrational states of OH. This is within 20% of the best theoretical results. The dependence on vibrational state is very nonlinear, which is also in agreement with theoretical results. Finally, the difference between the ν = 0 dipole moments of OH and OD is close to the expected value.
