5 The fundamental band, 350-1000 K

We base our approach on the original theoretical paper where the most accurate ab initio dipole moments are computed (Meyer et al. 1989) and the papers describing the computer model of this band at low temperatures (Borysow 1991; Borysow 1993). We used the same model as the one available on the Internet, but with the new lineshape parameters based on the semi-classical moments, now computed at temperatures from 350 to 1000 K for j₁=j₂=j'₁=j'₂=0. We used all significant induction terms: $\lambda_1 \lambda_2 \Lambda L$ = 0001, 0221, 0223, 2021, 2023, 2233 and the SK potential. We adopted lineshapes BC and K0 instead of the more advanced BB lineshapes used by Borysow (1991). All other parameters are computed by the model internally.
