abstract = {The performance of Density Functional Theory (DFT) methods
in predicting ethylene polymerisation and/or oligomerisation
activity in selected aluminium and scandium based complexes
was studied using both DFT and post-Hartree-Fock CCSD(T)
calculations. Whereas previous reports have drawn attention
to the underestimation of the barrier for the beta-hydrogen
termination process for a few aluminium based species, we
found that the same holds for the corresponding scandium
complexes. New, however, is the observation that apart from
underestimating the energy barrier connected to
beta-hydrogen termination, the insertion of ethylene is also
several underestimated by the DFT methods applied compared
to post-Hartree-Fock calculations up to the CCSD(T) level.},
