Spin-dependent band gap calculations

  1. Jan 23, 2013 #1
    Dear colleagues,
    I am trying to deal with quantum-chemical calculations of metal-containing coordination polymers, and I have a question which turned out to be difficult to me:

    If a system includes copper atoms, which implies that it has 'unpaired' electron, how to describe a band gap in this case? I mean we can estimate two different band gaps for 'spin-up' and 'spin-down' channels, but what should we take as a reference to compare with experimental data?

    If you can advise me some literature on this, it would be also great.

    Thank you
