>Is there any normalisation to be made? Dividing by the number of
molecules per unit cell (if there is one per >asymmetric unit, this would
refer to 8 for an orthorombic case, e.g.)?<br><br>QE gives the energy of the cell defined in the input. <br>

>I'm not sure, what the "reference" of the calculated Rydberg value is -
if it would be the whole cell, I would get >doubled energy values and
differences when I calculate a 2x1x1 supercell...<br>
<br> Yes. Yo can make the test. there my be a few details. If you double the cell in X direction, divide by 2 the number of k-points in the first direction. If the number of electron is odd, it may be necessary to do a spin polarised calculation. <br>
<br><br>
>The other way round: what does "per mole" really mean in a conversion of "some amount" to "a mole" (e.g.: >Joule to Joule/mol)...<br>Take the energy in Ry, multiply by the number of Avogadro, and convert to kJ. My only doubt is per mole o what ? Moles of supercells, molecules or atoms? I do not know. <br>
