Abstract

The Direct Numerical Diagonalization $technique^{1}$ has been applied to the two principal symmetric species of carbon dioxide. Incorporating recent new high resolution measurements made at the McMath Solar Facility at Kitt Peak National Observatory by Rinsland et $al^{2}$ and the 2-meter path difference Fourier transform spectrometer at AFGL, new values for the potential function and dipolar coefficients have been calculated. The results are compared with the potential functions calculated by earlier Direct Numerical Diagonalization efforts as well as the contact transformation approach. The results are also discussed in terms of the effects of truncation errors and completeness of basis sets. This work was supported by the Air Force Office of Scientific Research, through AFGL task 2310G1.
