We have measured the absolute intensities as well as N₂- and air- broadened half-widths of lines in the P- and R- branches of the v2- fundamental bands of CO₂ at temperatures between 170K and 296K employing a Fourier-Transform-Spectrometer with spectral resolution as high as 0.0016 cm^-1. Intensities and self-broadening coefficients of lines of water vapor in the 7000-8800cm^-1 region have also been measured at room temperature.
