TL;DR: The present calculation produces results in significantly better agreement with experiment than previous determinations of the potential energy surface, and the energies predicted with the new surface are sufficiently accurate to be useful for the assignment of new high-resolution spectra.

TL;DR: More than 5000 observed line intensities belonging to 120 vibrational bands of the 12C16O2 molecule selected from the literature have been used to fit 60 parameters of an effective dipole moment as mentioned in this paper.
Abstract: More than 5000 observed line intensities belonging to 120 vibrational bands of the 12C16O2 molecule selected from the literature have been used to fit 60 parameters of an effective dipole moment. The eigenfunctions of the effective Hamiltonian published in our recent paper have been used in the fits. The regions of ν 2 , 3ν 2 , 5ν 2 , 7ν 2 , 9ν 2 , and 11ν 2 bands have been studied. RMS deviations ranging from 2.9 to 13.3% depending on the frequency regions have been achieved. The quality of the fits and the extrapolation properties of the fitted parameters are discussed. The predictions of both line positions and line intensities for perturbed bands 21113←11102, 21113←11101, 40002←11102, 12212←02201, and 23301←02201 are given. The results are compared with the HITRAN-96 database.

TL;DR: In this article, the spectroscopic parameters of the (1 0 0 v 3 ) 1,2 vibrational states with v 3 = 0−6 have been obtained from a global rotational analysis of the six (1 − v 3 − 1) 1 − 2 emission bands (v 3 = 1−6) of the CO 2 + N 2 mixture excited by dc discharge.
