Room temperature values of self- and air-broadening and pressure shift coefficients for the 2201-0000 (30012-00001) combination band of 12C16O2 located near 6348 cm-1 were determined from analysis of high-resolution laboratory spectra. The results were obtained from analyzing eight self-broadened and twelve air-broadened spectra that were fit simultaneously with a multispectrum nonlinear least squares technique. All data were obtained using a natural isotopic sample of CO2 at a resolution of about 0.01 to 0.012 cm-1 with the McMath-Pierce FTS at the National Solar Observatory on Kitt Peak and a 6-m base path White cell. The path lengths varied between 24 and 121m and the sample pressures were in the 11 to 900 Torr range. Present results will be compared to values reported in the literature.\footnote J.
