The [Formula: see text] and [Formula: see text] transitions of the CO 2 + ion were photographed in emission under high spectral resolution. Analysis of the electronic band origin of the [Formula: see text] transition has provided rotational constants which are more refined and extensive than those previously known. The presence of a perturbation at J′ ~ 36.5 in the [Formula: see text] vibronic level was confirmed and a second stronger perturbation was shown to exist for values of J′ < 20.5.The four subbands 01 1 0 2 Π g –01 0 0 μ 2 Σ u , 01 1 0 2 Π g –01 2 0 2 Δ u 5/2, 01 1 0 2 Π g –01 2 0 2 Δ u 3/2, and 01 1 0 2 Π g –01 0 0 κ 2 Σ u of the Renner–Teller split [Formula: see text] vibronic transition 010–010 were identified and rotationally analyzed. The results lead to values of [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text].
