SELF-CONSISTENT ANALYSIS FOR LINE POSITIONS OF CARBON DIOXIDE

$^{1}$M.P. Esplin, R.J. Huppi, H. Sakai, G.A. Vanasse, and L.S. Rothman, ``Absorption Measurements of $CO_{2}$ and $H_{2}O$ at High Resolution and Elevated Temperatures,'' AFGL-TR-0057 (1982). This work was supported by the Air Force Office of Scientific Research.A high resolution Fourier transform spectrometer coupled with a high temperature (800k) absorption cell have produced spectra for carbon dioxide in the $1600 to 2500 cm^{-1}$ $region^{1}$. These new data provide access to very high rotational levels. The measurements have been combined with the best available high resolution observations in other regions of the infrared and a procedure has been implemented to provide a global set of constants. The self-consistent set of energy levels and rotational constants that are derived have been used ot predict the positions of $CO_{2}$ IR transitions of significance to problems of atmospheric option
