Abstract
High-resolution (ca. 0.0025 cm-1) Fourier transform infrared spectra of AsH2D were recorded in the regions of the As-H and As-D stretching fundamental bands ν1/ν5 and ν2, respectively, and analyzed. Strong resonance interactions between the bands ν1 and ν5, and also between the band ν2 and the bending overtone band 2ν4 were established. From transitions observed in the ν1 and ν5 bands ground state rotational energies for larger values of rotational quantum numbers than previously available could be determined. Thereof improved ground state rotational parameters were derived. More than 3200 assigned transitions corresponding to 1059 upper state energy levels which were almost equally distributed over the three stretching states were fitted with an rms-deviation of 0.00031 cm-1, which corresponds to experimental precision.
