    • X-ray dichroism implies excitations from inner shells, which are filled in the ground state and can therefore be “integrated out.” As a result, one-electron properties of valence states are probed in the x-ray region

    • Sum rules for pure (formula presented) or (formula presented) transitions were derived by representing valence-electron states within an (formula presented) basis. In this case, the pertinent order parameters are derived from the generators of rotation groups: the components of spin and orbital angular momentum. Such a formulation can be extended to include parity-conserving hybridization; for example, it can be shown that pure (formula presented) linear dichroism mixes (formula presented) and (formula presented) Discussion of these effects is beyond the scope of the current paper
