Both types of 1h1p excitation contribute significantly to the J coupling only when the energy differences between the ligand orbitals and the magnetically active orbitals are sufficiently small. Important to note is that, these excitations influence the ferromagnetic and antiferromagnetic components differently: dynamic charge polarization increases the antiferromagnetic contribution by reducing the effective difference between inter-and intra-site Coulomb interactions; in contrast, spin polarization increases the number of accessible configurations with unpaired electrons, stabilizing the high-spin (and intermediate) states and thereby enhancing the ferromagnetic component. As a result, spin polarization shifts the linear trends in the squared orbital energy difference diagrams, while dynamic charge polarization dampens the linear progression.
