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.
