In multiply bonded cations, we observe persistent diagonal FCFs that are promising for optical cycling, on the 1 2 Σ 1/2 → 1 2 ∆ 3/2 transition. Finally, our analysis of FCFs of selected transitions together with an inspection of the Dyson orbitals of involved states suggests that although the charge displacement often makes the transition unlikely for optical cycling, it is not the crucial design factor. The most promising candidates in the three identified optical cycling schemes (discussed in Section III D) are:
