Abstract: This dataset is generated from two composite infrared absorption cross section spectra of carbon tetrafluoride (CF4) in air at the temperatures 296.06(2) and 296.06(1) and the total pressures 375.08(71) and 748.83(74) Torr, respectively, in the range of 570–1975 cm-1. Every spectrum was split into 7 regions, containing an isolated absorption feature. This makes 14 *.dat files altogether.
Other: This work was done within the project “Metrology for climate relevant volatile organic compounds”, MetClimVOC. The project has received funding from EMPIR programme co-financed by the Participating States and from the European Union’s Horizon 2020 research and motivation programme.
Remark: description of the individual files: Each file contains three columns: 1. Wavenumber of the incoming radiation (in cm-1); 2. Absorption cross section (in cm^2/molecule); 3. Expanded uncertainty (in cm^2/molecule).
