Correlation consistent basis sets designed for density functional theory: Second-row (Al-Ar) (open access)

Correlation consistent basis sets designed for density functional theory: Second-row (Al-Ar)

Article presenting cc-pV(n+d)Z correlation consistent basis sets of double- through quintuple-ζ quality for the atoms Al-Ar that have been modified for use with density functional theory (DFT). These basis set modifications include truncation of high-angular momentum basis functions, recontraction of the s- and p-functions, and reoptimization of basis function exponents with generalized gradient approximation and hybrid-DFT functionals. The effects of basis set truncation, recontraction, and reoptimization are shown to improve convergence behavior in atomic energies as well as dissociation energies and enthalpies of formation.
