Abstract

The millimeter/submillimeter transitions of the ν₅–2ν₉interacting bands of HNO₃have been measured in the symmetric top limit. Torsional splittings in both vibrational bands have been observed. The 2ν₉splitting is due to the torsional motion of H around the NO whereas the ν₅splitting is due to the large mixing with 2ν₉. An analysis is presented in which a Fermi interaction, 2 sets of 2ν₉rotational constants, and one set of ν₅rotational constants are used to account for all of the perturbation and torsional splitting observed in the spectrum. The 860 lines used in this analysis are fit to 91 kHz.
