Abstract:	The rotational spectrum of AsH₂ in its ground X̃²B₁ electronic state has been recorded using a far-infrared laser magnetic resonance spectrometer. The AsH₂ radical was produced inside the spectrometer cavity by the reaction of arsine (AsH₃) with fluorine atoms. Hyperfine splittings from both ⁷⁵As and ¹H nuclei were observed, and analysis of the spectra has yielded accurate values for rotational, hyperfine, and Zeeman parameters.
