✦ Synopsis

A number of pure quadrupole resonances in the ground and (v_{4}=1) states of (\mathrm{AsH}{3}) have been measured using the radiofrequency-infrared double-resonance technique in a (\mathrm{CO}{2}) laser cavity. The ground state resonances were fitted together with all available radiofrequency and microwave data using the standard treatment. Strong vibration-rotation interactions between the (v_{2}=1) and (v_{4}=1) states affect the observed spectrum in the (v_{4}=1) state. The Hamiltonian model by Aliev and Hougen (J. Mol. Spectross. 106, 110-123(1984)) has been used. in the form of a computer program, to describe within the experimental uncertainties the new measurements in a combined analysis with all known experimental data in the (v_{2}=1) and (v_{4}=1) states. k. 1943 Academic Press.

This paper presents the analysis of the spectra of SiDF 3 in its vibrational ground and v 4 ϭ 1 states. The pure rotational spectrum of the ground state was measured up to 903 GHz ( JЉ ϭ 65). Rotational, quartic, and sextic centrifugal distortion constants were accurately determined. Furthermore the
