Dear CP2K users, <div><br></div><div>I am trying the reproduce an old paper that calculates de binding energies of oxygen to a heme molecule. According to this reference, different multiplicities for oxygen and heme should be taken into account. I've tried to calculate the different energies for the different multiplicity states, but I consistently get the same results no matter the value I set to the flag MULTIPLICITY. </div><div><br></div><div>I am sure I am overlooking something but I cannot figure it out... I would be very grateful if you could help me fix this. </div><div><br></div><div>I have copied the input file at the end of this email. </div><div><br></div><div>I am using CP2K5.1 . </div><div><br></div><div>Thank you in advance:</div><div><br></div><div>Salome</div><div><br></div><div><p><b><font size="1">&GLOBAL</font></b></p>
