Example potential energies (upper) and couplings (lower) from the LCAO model, for Mn+H with the Mn⁺(a⁷S) core in the ⁷Σ⁺ symmetry (left), and Ti+H with the Ti⁺(a⁴F) core in the ⁴Σ⁻ symmetry (right). A selected subset of states are labeled in the upper panels, and, for the covalent states, only the label of the target Mn or Ti atom is given; i.e. a hydrogen atom in its ground state is implied. Couplings H_1j at avoided crossings are plotted against the crossing distance R_c, and results are shown for the adiabatic and diabatic representations, with the values adopted in the circled calculations.
