Global analysis of the Comet-tail system of 12C16O+

doi:10.1088/1674-1056/22/7/073302

Abstract A global analysis of the ro-vibrational spectra of 19 bands in the comet-tail (A²Π_i-X²Σ⁺) system of the ¹²C¹⁶O⁺ cation is presented, and the precise molecular constants of the vibrational levels involved are obtained via a weighted nonlinear least-squares fitting procedure. Furthermore, the resultant precise equilibrium molecular constants enable us to achieve accurate Rydberg-Klein-Rees (RKR) potential curves for both the A and X states, yielding the accurate Franck-Condon factor and band origin of each band in this system.
