- High resolution transmissivity data have been generated for CO2/H2O/N2 mixtures.
- Temperatures are in the 500-1770Â K range.
- Measurements are available as Supplementary Material.
- HITEMP-2010 has been used to reproduce the measured data.
- HITEMP-2010 has proven to be an excellent database.
The objective of the work is validation of HITEMP-2010 at atmospheric pressures and temperatures reaching 1770K. To this end, spectral transmissivities at 1Â cmâ1 resolution and excellent signal-to-noise-ratio have been measured for 22 CO2/H2O/N2 mixtures. In this paper we consider the 450Â cmâ1-7600Â cmâ1 spectral range. The LbL calculations and their comparison with the measured spectra have clearly shown that HITEMP-2010 is an excellent database (superior to previous versions) for calculating emissivities and absorption coefficients for CO2 and H2O molecules in the 500-1770Â K range. Several absorption lines listed in HITEMP-2010 have not been observed in the measured spectra and/or are wrongly scaled with temperature. The complete (there are no missing bands) spectra spanning the 450-7600cmâ1 range are appended as Supplementary Material.
