摘要

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