gas mixture on the amount of arsine generated is investigated. The arsine production reaches a maximum for an argon‐to‐hydrogen ratio of unity indicating that metastable argon species act as energy transfer intermediates in the overall reaction. The generation of arsine and diarsine from easily handled solid arsenic by this technique makes it attractive as a possible arsenic source for the growth of compound

The IR spectrum of AsH in its ground3Σ–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 has been resolved, and the observation of the v= 2–1 and 3–2 hot bands of AsH has allowed an accurate determination of the vibrational anharmonicity, ωexe.
