Abstract

Highlights: Absorption cross sections of pure and broadened (H2 or He) propane from 150 to 210 K. Synchrotron radiation used to record spectra between 600 cm -1 and 1250 cm -1 . Physical conditions chosen to replicate atmospheres of the giant planets. Abstract: Absorption cross sections of cold propane, pure and broadened with H2 or He, have been recorded in the 650–1250 cm -1 region using an Enclosive Flow Cooling (EFC) cell located at the Australian Synchrotron Far-IR/THz beamline. The chosen temperatures range from 150 to 210 K to replicate similar atmospheric conditions of the giant planets. These cross sections have been normalized using data obtained from the Pacific Northwest National Laboratory, and can be used directly in comparisons with observed spectra and in radiative transfer models.
