Abstract
The interference of the absorption bands of H2O, CO2, and several gaseous biomarkers was analyzed in the middle and near-IR spectral region using the HITRAN2006 database. It was demonstrated that the problem o f the vibration-r o tation band interfere nce for detected and interfering gases is aggravated in the near-IR spectral region. This aggravation is caused not only by the decrease in the absolute band intensity for overtones and combination bands of the molecular vibrations but also by the relative increase in the absorption in H2O lines and high density of CO2 lines in the near-IR spectral region
