Crystal hamiltonian
In a crystal, we take the single particle hamiltonian to be H= H at+ U; (1) where H at is the hamiltonian for a single atom and U encodes all the di erences between the true potential in the crystal and the potential of an isolated atom. We assume U!0 at the centre of each atom in the crystal. The single particle states in the crystal are then WebCrystal-field Hamiltonian We note that three spin-allowed electronic transitions should be observed in the d-d spectrum in each case.We have, thus, arrived at the same point established in Section 3.5. This time, however, we have used the so-called weak-field approach. Recall that the adjectives strong-field and weak-field refer to the magnitude of …
