High-resolution infrared study of AsH2D: The stretching fundamental bands ν1/ν5 and ν2

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.
