Abstract

The CO₂ transmission function was calculated and compared with the experimental data in the spectral range of 450- 7600 cm^-1. The spectral ranges suitable for a determination of temperature and concentration of CO₂ were determined. The influence of polynomial degrees on errors of approximating the transmission function and the influence of a number of spectral regions on errors of determining the temperature and partial pressure were analyzed.
