The general theory is given of the orientation dependence of the labelling of electron and phonon states in crystals. All types of space group are considered. There is no effect for the space groups with point groups O h , D 6h , D 4h , D 2h , C 2h , and C i , and for the space groups D 3d 5and D 3d 6 . The space groups T 3 and T 5 are studied as examples.
