These links are not meant to be explored neccessarily, but to show the level of authority that the link provides; and besides, just the hints of what exists out there should be enough to explain....
[SO also, that means I'm not gonna fix "uncopiable" links]I did notice that the Fourier Transform Spectra
are used for the kind of high resolution spectroscopy needed to detects precise electronic effects (transitions).
THE LAST LINK is worth following as it is an academic site and also a public access type thing that contains lots of other relevant links.
So, here we go....

In the CO2 emission spectrum the most intense bands are those of the Fox, Daffendak, and Barker system [22], which are probably emitted by the excited CO2+ molecules.
CO2 emission spectra also displays the triplet and Angstrom band systems of the CO molecule.
CII and OII lines are also present in the CO2 spectrum, along with the [c-t] system of the CO+.
The excitation of the upper states, from the ground state molecule by proton impact is forbidden on the grounds of spin conservation (Wigner's Rule); but not forbidden by impacts of hydrogen or electrons.
Transition from the ground state to upper levels takes place without appreciable change in the internuclear distance, i.e., in agreement with the Franck-Condon principle.

CO2Emission in the 4-μm Region The (21^1^1)3--> (21^1^0)3 Transition Revisited
From spectra recorded at a resolution of 0.020 cm−1of the flame CH4+ O2at low pressure, six new vibrational transitions in Δv3= 1 with 2v1+v2= 5 had been recently identified [D. Baillyet al., J. Mol. Spectrosc.182, 10–17 (1996)] based on the HITRAN 92 predictions. New calculations have shown good consistency with our assignments except for one transition, namely, (21`1`1)3--> (21`1`0)3 for which discrepancies (reaching 0.2 cm−1) were found. It has been possible to resolve this issue using new emission spectra of CO2, vibrationally excited by active nitrogen and recorded with a Fourier transform spectrometer at a resolution of 6.3 × 10−3cm−1in the 4–5 μm spectral region.

The infrared spectrum of the airglow in the region 2 to 4 μ m has been measured with a two-beam interferometer carried to high altitude by a balloon. The Δ v = 1 sequence of OH bands is in evidence as well as an emission band of CO2. The emission spectrum of the airglow between 2 and 4 Mm has been observed....
