The high-resolution spectra of AsH3 in the 8130-8340 cm-1 region, which were assigned to the (310; A1), and (310; E1), and the (310; E2) local mode combination bands, have been recorded at a resolution of 0.01 cm-1 and rotationaliy analyzed. The spectroscopic parameters were obtained by least-squares fitting. The rotational energy levels were fitted for the (310; A1) state (21 levels in all) up to J = 5, for the (310; E2) state (43 levels in all) up to J = 7, and for the (310; E1) state (43 levels in all) up to J = 5. The complication of the rotational structure indicates rotational perturbation.
