Implication

Spectroscopic study reveals refined molecular constants and spin-vibronic term values in the CO2+ ion, highlighting precise structural parameters for carbon dioxide.

Key Points

Investigate the Ã2Πu → X̃2Πg electronic transition of the CO2+ molecular ion to establish precise rotational and vibronic constants.
Applied high-resolution Fourier transform emission spectroscopy in the 20,000 to 33,000 cm⁻¹ region.
Assigned and analyzed 62 bandheads, conducting detailed rotational analyses on 17 subbands for the first time.
Determined spectroscopic constants for the previously uncharacterized 102, 202, 302, and 402 levels of the X̃2Πg ground state.
Established an improved, comprehensive set of spin-vibronic term values, molecular constants, and band origins validated against existing literature.
