I could be wrong, but I think the values of the complex momentum matrix elements in the mommat2 file should be in units of momentum. In the atomic units (a.u.) system [ https://en.wikipedia.org/wiki/Atomic_units ], I believe the momentum element values are unitless or dimensionless. However,

Dear Wien2k users, Hello, I am currently working on obtaining the transition dipole moments of ZnO and Sapphire along specific paths in the Brillouin Zone using optic. I calculated the momentum matrix elements (the ones in case.mommat2) but I seem to be getting values slightly lower than the ones
