Energy-adjusted a b i n i t i o pseudopotentials for the first row transition elements
Abstract
Nonrelativistic and quasirelativistic ab-initio pseudopotentials representing the Ne-like X(Z−10)+ cores (X=Sc–Zn) of the first row transition metals and optimized (8s7p6d1f )/[6s5p3d1f ]-GTO valence basis sets for use in molecular calculations have been generated. Excitation and ionization energies of the low lying states of Sc through Zn from numerical HF- as well as SCF- and CI(SD)-pseudopotential calculations using the derived basis sets differ by less than 0.1 eV from corresponding all-electron results.
