Subject: identifying single configuration systems

All

Is it possible to tell, a priori, if a system can be reasonably and
reliably represented by a single configuration method?

Are there any systems that generally fail? transition states,
partially filled orbitals, partially filled _degenerate_ orbitals,
etc.

Thanks,
Roy Jensen
