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.

Laser Stark

Laser Stark spectra have been observed in the (020) ← (010) hot band of H216O. A near coincidence between the 15–14 P(11) line of the 13C18O laser at 1677.228 cm−1 and the 606 ← 515 rovibrational transition of H2O as analyzed with the result: [Formula: see text]. Using the same laser line, an infrared–radiofrequency double resonance signal arising from the 422–515 transition within the (010) vibrational state was measured to be: 2159.98 ± 0.3 MHz.
