text: (1) Since we are dealing with promotion of electrons from ground to excited states, the energy separation between filled and empty orbitals (HOMO-LUMO separation) has an important effect, i.e. low-lying unoccupied molecular orbitals of the correct symmetry (see (2) below) result in large paramagnetic (high-frequency) shifts.
