The high resolution spectrum of arsine in the region of 11 470-11 650 cm-1 was recorded by a sensitive laser photoacoustic apparatus. The vibration-rotation transitions of the local mode pair of bands (600A1/E) were assigned and their major vibration-rotation parameters were obtained by least-square fitting. The results indicate that the selection rules on the quantum number k have no effect in the high J values owing to strong Coriolis coupling. In addition, the intensities of vib-rotational transitions were estimated by comparison with standard water lines.
