The absorption coefficient of propane has been measured using a low-power CO<sub>2</sub> laser at a variety of wavenumbers over the range 940-1081 cm<sup>-1</sup>. At 944 cm<sup>-1</sup> the absorption coefficient of propane was found to vary linearly with pressure, its value being 8.5*10<sup>-5</sup> cm<sup>-1</sup> Torr<sup>-1</sup>. This coefficient was essentially unaltered by adding nitrogen to propane to produce an atmospheric mixture.
