Title - Cross Section IR Spectroscopy of Hydrocarbons in Planetary Atmospheres
Absorption cross sections of cold propane (C3H8), pure and broadened with H2 or He, were recorded at two sites, the Canadian Light Source (CLS) facility using either the synchrotron or internal glow-bar source depending on the required resolution and an Enclosive Flow Cooling (EFC) cell located at the Australian Synchrotron Far-IR/THz beamline. Measurements were made in the far-IR region (650-1300cm−1) for a range of pressures up to 100 Torr and temperatures from 150 to 292K. Infrared absorption cross-sections were derived from the spectra and can be used to interpret astronomical observations of giant planets such as Jupiter and Saturn as well as exo-planets.
Access to the Data
Documentation consists of 3 published papers
Data Derived
The data are organized in 3 collections of CSV files with detached XML labels (hydrogen and helium broaden propane cross section collections and a separate collection containing unbroadened propane cross sections.
