Abstract

The high resolution Fourier transform spectra of AsH₃ in the region of 9720-9900 cm^-1, which had been recorded at a resolution of 0.015cm^-1, were assigned to the (500; A₁) and (500; E) local mode overtones and rotationally analyzed. The effective spectroscopic parameters were obtained by nonlinear least-squares fitting the vibration-rotational Hamiltonian with the rotational energy levels up to J = 6 (98 levels in all) included. The evolution of the rotational energy patterns from υ = 1 to υ = 6 shows that the tendency of normal mode to local mode vibration evolution has been stopped by perturbations in relatively high energy region.
