Double Resonance Spectroscopy

Twenty-nine rotational transitions of HNO in the Ã1A″(000) excited state have been measured by microwave-optical, and radio-frequency-optical double resonance spectroscopy. Most of the observed lines are found to be perturbed by a few to a few hundred MHz. Improved values have been obtained for the rotational constants B and C and for the centrifugal distortion constant δJ. MODR lines have also been observed between levels of the Ã1A″ excited state, high rovibronic levels of the [Formula: see text] ground state, and levels of the ã3A″ state. One of the lines shows a larger magnetic effect, suggesting a perturbation by a level of the ã3A″ state.

The perturbations in the 41 level of the Ã1A2 excited state of thioformaldehyde (H2CS) are shown to be produced by interactions with the 2131, 4262, and 63 levels of the ã3A2 state.Some of these perturbations have been studied with megahertz resolution using the techniques of intermodulated fluorescence and microwave-optical double resonance. A particularly clear example involving hyperfine levels is found in the interaction of the 170.17 (41) level of the Ã1A2 state with the 17 181,18 (4262) level of the ã3A2 state.
