dipole matrix element in Coulomb-meter (Cm)
« on: April 2, 2013, 14:07 »
Dear Developers of ATK,

is it possible to extract or save the dipole matrix element(in Coulomb-meter(Cm)) ?

best regards

One more question about the unit of dipole moment matrix. With ATK, we have e*Bohr – is this electric charge in CGS times Hydrogen Bohr Radius in Angstroms?

Thank you !

1 Bohr = 0.529177249 Angstrom and e is the electron charge

Dear Anders and ATK team,

I need your help again. From these dipole matrix calculation I need to know this transition between what and what?  If the code does not give the symmetry but tells what the dipole is, for example : <Band1|Z|Band2> and <Band1|X|Band2>  ?  is it possible to know from which band ? I need to know for each relevand band.

This is not a dipole moment for a particular transition, it's for the whole system. The quantity mostly makes sense for molecules.
