In a laboratory study of phosphine (PH3), over 1000 line intensities are measured at 0.002 cm-1 resolution in the 830 to 1310 cm-1 spectral region containing the two lowest fundamental vibrational bands of this molecule. These measurements are modeled to 1.9% using five intensity parameters that includes three Herman-Wallis type terms. The integrated intensity for the region is 156.4 (2) cm-2 atm-1 at 296 K.. The corresponding assignments and line positions from previous work [L. Fusina and G. Di Lonardo, J. Mol. Struct. v517-518, pp67-78 (2000)] are combined with the present intensity study to provide an improved PH3 database for planetary studies.

Part of the research described in this paper was performed at the Jet Propulsion Laboratory, California Institute of Technology, under contract with The National Aeronautics and Space Administration. This research was supported, in part, by the United States Department of Energy, Office of Basic Energy Sciences, Chemical Sciences Division and the experimental part was performed at the W. R, Wiley Environmental Molecular Science Laboratory, a national scientific user facility sponsored by the Department of Energy's Office of Biological and Environmental Research located at the Pacific Northwest National Laboratory. Pacific Northwest National Laboratory is operated for the United States Department of Energy by Battelle under contract DE-AC06-76RLO 1830.
