Abstract
Preliminary results from rotational analysis of new high-resolution spectra of the A3Π–X3Σ− transition of OH+ and OD+ are reported. The line assignments for low rotational quantum numbers given by previous authors have been found to be in error by up to 10 cm−1. Various irregularities in the Λ doubling of the A3Π state can probably be explained by strong interaction between the b1Σ+ and A3Π states. An analysis of rotational perturbations in the bands of OH+ suggests that the b1Σ+ electronic state lies about 1200 ± 50 cm−1 above the A3Π state.Keywords
