Absorption properties of infrared active gases at high pressures - II. N2O and CO.
Abstract
Absorptions of the near infrared N2O and CO bands were measured at high pressures. The band intensities were found to be 0.153±0.002, 1.14±0.01, 1.67±0.01, 0.035±0.002, 3.25±0.02 and 49.9±0.3 cm-1/(atm-cm)STP for the 2.0, 2.1, 2.3, 2.5, 2.6 and 2.9 μm N2O bands, respectively, and 2.07±0.02 cm-1/(atm-cm)STP for the first overtone CO band. It was also found for both molecules that the spectra measured under large absorber amounts are smaller in the band wings than those calculated from the Lorentzian line profile. This discrepancy is discussed in terms of non-Lorentzian behavior of the line profile.
