Journal ArticleDOI
One- and two-electron integrals over cartesian gaussian functions
TL;DR: In this article, a formalism is developed which allows overlap, kinetic energy, potential energy and electron repulsion integrals over cartesian Gaussian functions to be expressed in a very compact form involving easily computed auxiliary functions.
Journal ArticleDOI
Effects of electron repulsion in conjugated hydrocarbon diradicals
Journal ArticleDOI
Size consistency in the dilute helium gas electronic structure
TL;DR: In this paper, a new formula for correcting double-excitation Cl result for the effects of higher excitations is suggested, and the correct form of the effective hamiltonian for a coupled-electron-pair-approximation is discussed for a dilute gas of helium atoms.
Journal ArticleDOI
Ground-state correlation energies for atomic ions with 3 to 18 electrons.
Subhas J. Chakravorty,Steven R. Gwaltney,Ernest R. Davidson,F. A. Parpia,Charlotte Froese Fischer +4 more
TL;DR: The correlation energies for 3- to 10-electron atomic ions are recomputed using more recent experimental and theoretical data and the correlation energies obtained from some density-functional models are also compared to these correlation energy data.
Journal ArticleDOI
Comment on ``Comment on Dunning's correlation-consistent basis sets''
TL;DR: By using a general linear transformation of Dunning's contracted basis set, the contraction length can be reduced even more than noted in the Comment by Hashimoto et al, which results in a considerable savings in computer time.
