CCL:broken symmetry



 Hello!
 
IB4ve just started to make some investigations about antiferromagnetical coupling in binuclear complexes. But IB4ve got problems to understand the principle of the broken symmetry approach. What do I have to calculate to get the right values? I would be very glad if someone could probaly send me some input file for gaussian to see an example.
 Thank you very much!
