We have begun a systematic reinvestigation of the CO₂ spectrum in the 4000 - 9000 cm^-1 range using the McMath-Pierce Fourier transform spectrometer at the Kitt Peak National Solar Observatory. Fits to more than 100 vibrational bands illustrate that it is possible to obtain rms uncertainties as low as 2×10^-5 cm^-1 for strong bands and uncertainties better than 2×10^-4 for all bands with S⁰_v > 0.01×10^-22 cm^-1/(molecule cm^-2). We will also present the first analysis of several ¹⁸O¹²C¹⁸O and ¹⁶O¹³C¹⁸O bands. All results will be compared to the data available in the HITRAN database and evaluated relative to the needs of atmospheric remote sensing.
