46. The dipole-dipole interaction cannot be separated in a clean fashion from other interactions at short distances. We chose to work with a model interaction that is mathematically umambiguous. All the deviations with respect to this model interaction (that will probably appear at short distances) will be included in the SR part.
47. The SR part also contains higher Coulomb terms like dipole-octupole and octupole-octupole interactions.
