As a check, we also did a Stable=Opt calculation starting from the closed-shell singlet (Job 7).Since G09 Rev. D.01, “Stable=Opt” starting from closed-shell singlet is able to get to the antiferromagnetic solution in this case. The closed-shell singlet was unstable, as expected, and a subsequent Stable=Opt found a …
