High-temperature, High-resolution Measurements of CO2 in the Region of 2200 to 2400 Cm-1

The CO2 vibrational-rotational transition in the 4.3-micrometers region (2200 to 2400/cm) was observed at an elevated temperature of 600 K. The technique of Fourier spectroscopy was used to observe the spectrum with a resolution of 0.006/cm. The identified lines are expressed in terms of the molecular constants determined through the least-square-error fitting method.
