| Abstract: | Microwave spectra of three deuterated arsines have been measured and analysed. For AsD3 distortion moment transitions have been observed for the first time, in the form of the K = ±1 ← ∓2 cluster; their frequencies have been combined with those of previously observed “normal” transitions to give rotational, centrifugal distortion, and 75As hyperfine constants. For AsH2D and AsHD2, the measurements have been extended considerably and now include for the first time R-branch transitions; similar spectroscopic constants have been evaluated. The data have been combined with earlier results for AsH3 and with vibrational data in a harmonic force field analysis. Both ground state average (rz) and equilbbrium (re) structures have been estimated. |
