Dear Petko

Yes, I think so.

Betreff: [CP2K:14316] Broken Symmetry and MULTIPLICITY


Dear all, may someone advice me on the following.

I want to get the proper antiferromagnetic coupling of two Cu2+ ions in a bimetallic complex. For this purpose I use the &BS subsection. Mu question concerns the MULTIPLICITY keyword in this case. What should be the  MULTIPLICITY in this case? If I specify only  MULTIPLICITY 1, which is the actual spin state, cp2k will do non-spinpolarized calculation, which is not the  case.  That is why I use UKS  T  and MULTIPLICITY 1. 
Is that correct setting?

Best regards,

Petko
