 Title: THE DISTORTION MOMENT SPECTRUM OF $ASO_{3}$ AND THE ROTATIONAL SPECTRA OF $AsH_{2}O$ AND $AsO_{2}H$ Creators: McRae, G. A.; Wong, M.; Gerry, Michael C. L.; Ozier, I. Issue Date: 1985 Publisher: Ohio State University Abstract: This talk examines the rotational spectra of the deuterated arsines. In the first instance we shall look at forbidden centrifugal distortion transitions of $AsD_{3}$. Fourteen Q branch transitions, with peak absorption coefficients on the order of $10^{11} cm^{-1}$, in the frequency range 13.0 to 14.3 GHz and with J in the range 8 to 24 have been measured and assigned. The assignment was based on the experimentally observed quadrupole splitting and on the goodness of a global fit that included both the distortion spectrum reported here, and previously measured allowed transitions. For the partially deuterated forms, an analysis of a large number of allowed hyperfine split lines is examined. The frequencies of all these transitions ranged from 9 to 300 GHz., for J’s up to 16. A harmonic force field, $r_{2}$ structure and equilibrium structure for arsine will also be presented.
