CHF3 infrared absorption cross sections (single components)

This dataset contains infrared absorption cross section spectra of fluoroform (CHF3) in synthetic air at the temperatures 296.90(8) and 296.07(8), and various total and partial pressures in the wavenumber range of 600-1940cm-1. Every spectrum was splitted into 6 regions containing an isolated absorption feature, making a total of 12 *.dat files. Every single file contains a different number of spectra, representing only spectra used in the creation of the corresponding composite spectrum (available at doi.org/10.7795/720.20250708).

If the recorded experimental absorption at a certain wavenumber exceeded the cut-off limit (i.e., the spectrum was saturated), its uncertainty was set to 1.00E+10 and absorption cross section itself was set to zero to avoid misreading of empty values. In spectra 1b and 5b absorptions (and, subsequently, cross sections) were manually set to zero due to the remaining CF4 absorption feature around 1280 cm-1 (v3 band); the expanded uncertainties for these points were also manually changed to 1.00E+10 to exclude these points from consideration and weighted averaging.
