Abstract

The results of laboratory measurements of high-resolution infrared spectra of carbon dioxide in the region near 10 μm at several temperatures and pressures are described. Spectra of the CO2 laser bands centered at 961 and 1064 cm−1 were collected at a resolution of 0.005 cm−1 with the gas at temperatures between 50 and 150°C. The self-broadened rotation–vibration line shapes were modeled using a nonlinear least-squares regression technique. Careful attention was given to the problem of base line correction. The temperature exponent of the pressure-broadening coefficient was estimated for thirty lines. The linewidths obtained previously using indirect methods compare well to data obtained in the present investigation.
