Abstract

Highlights: High resolution Infrared spectra of propane (C3 H8 ) in 600–1250 cm -1 region. Absorption cross sections at four temperatures from 292 K to 205 K. Cross sections for pure propane and broadened with hydrogen. Useful for interpretation of spectra of the Giant Planets. Abstract: Fourier transform infrared absorption cross-sections of pure propane (C3 H8 ) and propane broadened with H2 have been calculated from transmittance spectra recorded at temperatures from 292 K to 205 K. Transmittance spectra were recorded at the Canadian Light Source (CLS) Far-Infrared beamline, utilizing both the synchrotron source and the internal glowbar source. The absorption cross-sections have been calibrated to Pacific Northwest National Laboratory (PNNL) reference cross-sections of propane and can be used to interpret astronomical observations of giant planets such as Jupiter and Saturn as well as exoplanets.
