Submillimetre-wave spectra of AsH and AsD radicals in the X3∑- electronic state

Rotational lines of AsH and AsD radicals in their X 3∑- ground state have been observed in the submillimetre-wave region for the first time. The AsH radical was generated by de-glow discharge in pure AsH3 gas, and the AsD radical was generated by the reaction of arsenic powder with a mixture of D2 and O2 gases in a de-glow discharge. Three rotational transitions of AsH with hyperfine structure (N,J = 0,1-1,0 2,1-1,1 3,2-2,2) were measured in the frequency region 120-338 GHz, and five transitions (N,J = 0,1-1,0 2,1-1,0 2,2-1,1 4,3-3,3 5,4-4,4) of AsD in the region 173-440 GHz. The molecular constants, including the rotational constants, the spin-rotation coupling constant with the centrifugal distortion term and hyperfine coupling constants associated with the arsenic, hydrogen and deuterium nuclei, were precisely determined by least-squares fitting to the observed spectral lines. Using the results of both AsH and AsD, the Born-Oppenheimer equilibrium bond length was derived, where the adiabatic correction was taken into account: reBO = 1.522 370 (86) A.

The IR spectrum of AsH in its ground 3Σ- state has been recorded using CO laser magnetic resonance (LMR).Several molecular parameters of AsH have been determined for the first time.In particular, arsenic nuclear hyperfine structure h
Spectroscopic observation of the b 1Σ+ -> 3Σ- transition of AsH

Emission lines of the b1Σ+ ->3Σ- transition of AsH radicals have been detected in the fluorescence of a dc-glow-discharge of arsine in hydrogen.From measurement of line positions of the (0,0), (1,1), and (2,2) Q branches and the (0,0) P and R branches, the molecular constants of the b1Σ+ state were determined: Te = 14 178.0 cm-1, B0 = 7.2467 cm-1, D0 = 3.1528*10-4 cm-1, ωe = 2213 cm-1, ωexe = 47.5 cm-1, re = 152.937 pm.
