 The adsorption energy is given by:$ E_{ad} = E_{CO+graphene} - E_{CO} - E_{graphene}$ The adsorption energy is given by:$ E_{ad} = E_{CO+graphene} - E_{CO} - E_{graphene}$
  
-This means that you also have to make an auxiliary geometry optimization calculation using <chem>CO</chem> in vacuum, using the same settings as for the other calculations except for the periodicity. Use a large enough cell (~ 15 Å) and [[https://manual.cp2k.org/trunk/CP2K_INPUT/FORCE_EVAL/SUBSYS/TOPOLOGY/CENTER_COORDINATES.html|''CENTER_COORDINATES'']] for this.+This means that you also have to make an auxiliary geometry optimization calculation using <chem>CO</chem> in vacuum, using the same settings as for the other calculations except for the periodicity.
