Accurate potential energy curves, spectroscopic parameters, transition dipole moments, and transition probabilities of 21 low-lying states of the CO+ cation

This work calculates the potential energy curves and spectroscopic parameters of all the states and computes the transition dipole moments between different Λ-S states. The FC factors and Einstein coefficients of many emissions are evaluated. The radiative lifetimes are determined for the vibrational levels of several states. Spectroscopic routines for observing these states are proposed. The SOC effect on the spectroscopic parameters and vibrational levels is insignificant for all the Ω states except for the vibrational levels of 22Δ3/2 and 22Δ5/2 states. The spectroscopic parameters, vibrational levels, transition dipole moments, and transition probabilities reported in this paper can be considered to be very reliable and can be used as guidelines for detecting these states spectroscopically in the near future.102.
