Tables and shows the SOC-corrected states with their energies, transition dipole moments, and radiative lifetimes. SOCs mix the non-relativistic states and the extent of mixing is determined by the energy gaps between the states (which varies between the cations) and the magnitude of the Breit-Pauli Hamiltonian matrix elements (which are larger for cations containing heavier atoms). The energy shifts due to the SOCs do not exceed 0.1 eV and cause splittings of the Π and ∆ states. Crucially, the SOC-perturbed states show non-vanishing transition dipole moments between the ∆ and Σ states in the range of 0.01 a.u.
