Hi Liu
you will need to define some of the closed orbitals as core, because in
ci, closed "orbitals do not form part of the active space, i.e., they
are doubly occupied in all reference CSFs; however, in contrast to the
core orbitals (see CORE), these orbitals are correlated through single
and double excitations."
