Propane absorption band intensities and band model parameters from 680 to 1580cm-1 at 296 and 200 K

Band intensities and profiles have been measured for the propane absorption bands from 680 to 1580cm^-1 at 296 and 200 K. This work was stimulated by the discovery of several propane bands in the spectrum of Titan by the Voyager 1 spacecraft. The low temperature laboratory data show that the bands become narrower and the Q branches of the bands somewhat stronger than they are at room temperature. Random band model parameters were determined over the entire region from the 42 spectra obtained at room temperature.
