Dear Thomas and Alex, thanks a lot for the reply.

Dear Alex. My problem is that in the case of O2 the ground state is triplet. That was the reason why I have started with ROHF orbitals. But probably it was my mistake, and the choise that you suggest is
better.
>For O2, you would need RHF orbitals of O22+ system.
