Cross section data for 12C16O2

Reminder: the cross sections provided by this page are calculated at zero-pressure (i.e. Doppler-broadened lines only). If you enter your email address below it will only be used to inform you of fixes to the service in case it fails. Alternatively, please email christian.hill@ucl.ac.uk.

The default format of the .sigma data file is a single column of cross section points (in cm2/molec), one for each wavenumber bin selected, starting at νmin and spaced by Δν. Select two-column output below if you want each cross section point preceded explicitly by the wavenumber at the centre of the bin it applies to.

Online absorption cross section service: this 12C16O2 cross section has been generated from the line list UCL-4000 [Yurchenko et al, 2020] using the procedure described in [Hill et al. (2013)].
