+	abstract = {A new formulation of the spin-flip (SF) method is presented. The electronic wave function is specified by the definition of an active space and through α-to-β excitations from a Hartree--Fock reference. The method belongs to the restricted active space (RAS) family{,} where the CI expansion is restricted by classifying the molecular orbitals in three subspaces. Properties such as spin completeness{,} variationality{,} size consistency{,} size intensivity{,} and orbital invariance are discussed. The implementation and applications use a particular truncation of the wave function{,} with the inclusion of hole and particle contributions such that for fixed active space size{,} the number of amplitudes is linear in molecular size. This approach is used to investigate single and double bond-breaking{,} the singlet--triplet gap of linear acenes{,} electronic transitions in three Ni(ii) octahedral complexes{,} the low-lying states of the 2{,}5-didehydrometaxylylene (DDMX) tetraradical and the ground state multiplicity of 28 non-Kekul{\'e} structures. The results suggest that this approach can provide a quite well balanced description of nearly degenerate electronic states at moderate computational cost.},

+	abstract = {In this paper{,} we report the development{,} implementation{,} and assessment of a novel method for describing strongly correlated systems{,} spin--flip non-orthogonal configuration interaction (SF-NOCI). The wavefunction is defined to be a linear combination of independently relaxed Slater determinants obtained from all possible spin--flipping excitations within a localized orbital active-space{,} typically taken to be the singly occupied orbitals of a high-spin ROHF wavefunction. The constrained orbital optimization of each CI basis configuration is defined such that only non-active-space orbitals are allowed to relax (all active space orbitals are fixed). A number of simplifications and benefits arise due to the fact that only a restricted number of orbital rotations are permitted{,} (1) basis states cannot coalesce during SCF{,} (2) basis state optimization is better conditioned due to a larger effective HOMO--LUMO gap{,} (3) smooth potential energy surfaces are easily obtained{,} (4) the Hamiltonian coupling between two basis states with non-orthogonal orbitals is greatly simplified. To illustrate the advantages over a conventional orthogonal CI expansion{,} we investigate exchange coupling constants of bimetallic complexes{,} the avoided crossing of the lowest singlet states during LiF dissociation{,} and ligand non-innocence in an organometallic complex. These numerical examples indicate that good qualitative agreement can be obtained with SF-NOCI{,} but dynamical correlation must be included to obtain quantitative accuracy.},

+	abstract = {The restricted active space spin-flip (RAS-SF) approach is a multistate{,} spin-complete{,} variational and size consistent method applicable to systems featuring electronic (near-)degeneracies. In contrast to CASSCF it does not involve orbital optimizations and so avoids issues such as root-flipping and state averaging. This also makes RAS-SF calculations roughly 100--1000 times faster. In this paper RAS-SF method is extended to include variable orbital active spaces and three or more spin-flips{,} which allows the study of polynuclear metal systems{,} triple bond dissociations and organic polyradicals featuring more than four unpaired electrons. Benchmark calculations on such systems are carried out and comparison to other wave-function based{,} multi-reference methods{,} such as CASSCF and DMRG yield very good agreement{,} provided that the same active space is employed. Where experimental values are available{,} RAS-SF is found to substantially underestimate the exchange coupling constants{,} if the minimal active space is chosen. However{,} the correct ground state is always obtained. Not surprisingly{,} inclusion of bridge orbitals into the active space can cause the magnitude of the coupling constants to increase substantially. Importantly{,} the ratio of exchange couplings in related systems is in much better agreement with experiment than the magnitude of the coupling. Nevertheless{,} the results indicate the need for the inclusion of dynamic correlation to obtain better accuracy in minimal active spaces.},
