摘要：

The IR spectrum of AsH in its ground (3) Sigma(-) 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, omega(e)x(e). Other molecular parameters have been determined more accurately, since Lamb-dip spectra have been recorded, and Delta Omega = +/-1 transitions of AsH in its X (3) Sigma(-) state have been measured.
