Dear PWscf users,<br> For a semiconductor, the transition dipole moment is useful for determining if transitions are allowed between valence bands and conduction bands. I have searched forum, and got no information concerning about transition dipole moment. Can PWscf calculate "Transition dipole moment"? <br>
