The rotational spectrum of AsH 2 in its ground X Λ2B 1 electronic state has been recorded using a far-infrared laser magnetic resonance spectrometer. The AsH 2 radical was produced inside the spectrometer cavity by the reaction of arsine (AsH 3 ) with fluorine atoms. Hyperfine splittings from both 7

The rotational spectrum of AsH in its metastable a 1 D state has been recorded using a far-infrared laser magnetic resonance spectrometer. The AsH radical was produced inside the spectrometer by the reaction of arsine (AsH 3 ) with fluorine atoms. Hyperfine splittings from both 75 As and 1 H nuclei
The gas phase reaction of OH radicals with hydrogen iodide (HI) has been studied using a Laser Photolysis-Resonance Fluorescence (LP-RF) apparatus, recently developed in our group. The measured rate constant at 298 K was (2.7 2 0.2) X lo-" cm3 molecule-' s-'. This rate constant is compared with the

Measurements of pressure-broadening and cross-relaxation rates of rotation-inversion transitions in the n 4 band (1470-1600 cm 01 ) of NH 3 perturbed by CO 2 are reported. Pressure-broadening parameters were measured at a low pressure of CO 2 (0-180 Torr). At high pressure, the two lines of the doub
