Direct interband dipole-transition selection rules for the O/sub h/3 space-group compounds

The irreducible representations associated with states of dipole symmetry have been calculated for the space groups O/sub h/3, the space group with the correct symmetry for A-15 phase compounds. Also assembled are the character tables of the O/sub h/3 group. Thus all thedirect interband dipole-transition selection rules for A-15 compounds can easily be determined
