The weak infrared spectrum of CO2–Ar corresponding to the (0111) ← (0110) hot band of CO2 is detected in the region of the carbon dioxide ν3 fundamental vibration, using a tunable OPO laser source to probe a pulsed supersonic slit jet expansion.

The gas phase spectrum of N2H2 has been investigated in the region of 7.6 μm at a resolution of about 0.06cm−1. Two bands have been identified; one, near 1288 cm−1, is a type C band and must correspond to ν4 (the hitherto unidentified Au torsional mode), and the other, near 1317 cm−1, is a type A–B hybrid and corresponds to ν6 (the Bu bending mode). Analysis of the spectrum is complicated by the simultaneous presence of strong A-type and B-type Coriolis interactions which couple the observed levels.

The correlated-k approach is compared with the exact line-by-line calculations for thermal radiative transport in highly nonhomogeneous media containing water vapor and carbon dioxide. It is shown that the magnitude of the spectral interval over which k-distribution functions are generated can be increased up to approximately 1000 cm−1 for water vapor and 500 cm−1 for carbon dioxide, with only a slight loss of accuracy. Different solution techniques of the radiative transfer equation in nonhomogeneous media are used and compared. The wide band correlated-k method and a simplified approach to the exponential wide band correlated-k method are shown to provide very good results for the cases considered. The calculations include the entire infrared spectrum of water vapor and carbon dioxide for temperatures up to 2500 K.
