چکیده انگلیسی
Previously we obtained self-broadened halfwidth and self-induced shift coefficients at room temperature for 15 near infrared CO2 bands between 4750 and 7000 cmâ1 [R.A. Toth, L.R. Brown, C.E. Miller, V.M. Devi, D.C. Benner, J. Mol. Spectrosc., 239 (2006) 243-271]. The present study expands our work on the near infrared line parameters of CO2 to include air broadening coefficients. Here we report nearly 400 air-broadened half width and air-induced pressure shift coefficients spanning 11 different CO2 vibrational bands in the 4750-7000 cmâ1 region. Retrievals have been performed using Voigt line profiles over three distinct spectral intervals: (a) 4750-5200 cmâ1, covering the 20011 â 00001, 20012 â 00001, and 20013 â 00001 Fermi Triad and three associated hot bands 21111 â 01101, 21112 â 01101, 21113 â 01101; (b) 6100-7000 cmâ1, covering the 30011 â 00001, 30012 â 00001, 30013 â 00001 and 30014 â 00001 Fermi Tetrad; (c) near 6950 cmâ1 for the 00031 â 00001 overtone band. The air-broadened halfwidth and air-induced pressure shift coefficients have been modeled with empirical expressions and compared to other measurements available in the literature.
