- High resolution absorption cross sections of propane (C3H8) in the far-IR (600-1200Â cmâ1).
- Cross sections for pure and He broadened propane.
- Measurements performed between 200-298Â K.
- Can be used for quantification of propane in giant planets.
Infrared absorption spectra for pure and He broadened propane have been recorded in the far-IR region (650-1300Â cmâ1) at the Canadian Light Source (CLS) facility using either the synchrotron or internal glowbar source depending on the required resolution. The measurements were made for 4 temperatures in the range 202-292Â K and for 3 pressures of He broadening gas up to 100Â Torr. Infrared absorption cross sections are derived from the spectra and the integrated cross sections are within 10Â % of the corresponding values from the Pacific Northwest National Laboratory (PNNL) for all temperatures and pressures.
