✦ Synopsis

We have investigated the saturation spectrum of the (\nu_{2}) fundamental of arsine. (\mathrm{AsH}{3}), at (906.75157863(85) \mathrm{cm}^{-1}) with a resolution of (200 \mathrm{kHz} . \mathrm{CO}{2}) laser sidebands at microwave modulation frequencies were used for the measurements between 890 and (988 \mathrm{~cm}^{-1}). Quadrupole hyperfine structure as well as vibration-rotation splitting of (K=3) and (K=6) levels have been investigated. In addition, an interaction between these two effects has been observed. Both effects have been included into the diagonalization of the energy matrix. The standard deviation of the fit, including MW and RF data, is (111 \mathrm{kHz}). This work was partly undertaken to contribute to calibration standards for Fourier transform and diode laser spectrometers. (c) 1994 Academic Press. Inc.

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 radiofrequenc

The high-resolution (0.005 cm -1 ) Fourier transform infrared spectrum of PH 3 is recorded and analyzed in the region of the fundamental stretching bands, ν 1 and ν 3 . The ν 2 + ν 4 and 2ν 4 bands are taken into account also. Experimental transitions are assigned to the ν 1 , ν 3 , ν 2 + ν 4 , and
