<i>A</i> <i>b</i> <i>i</i> <i>n</i> <i>i</i> <i>t</i> <i>i</i> <i>o</i> effective core potentials for molecular calculations. II. All-electron comparisons and modifications of the procedure
Recently methods have been developed [L. R. Kahn, P. Baybutt, and D. G. Truhlar, J. Chem. Phys. 65, 3826 (1976)] to replace the core electrons of atoms by ab initio effective co...
<i>A</i> <i>b</i> <i>i</i> <i>n</i> <i>i</i> <i>t</i> <i>i</i> <i>o</i> effective core potentials: Reduction of all-electron molecular structure calculations to calculations involving only valence electrons
A formalism is developed for obtaining ab initio effective core potentials from numerical Hartree–Fock wavefunctions and such potentials are presented for C, N, O, F, Cl, Fe, Br...
Non-empirical pseudopotentials for molecular calculations
Abstract The ability of the atomic pseudopotential proposed in Part I to reproduce the all-electron basis set extension and correlation effects in molecules has been tested on F...
The effect of 1<b>s</b> correlation on <i>D</i> <i>e</i>, <i>r</i> <i>e</i>, and ω<i>e</i> of first-row diatomics
A series of De, re, and ωe ab initio spectroscopic data for N2, O2, F2, CO, NO, and HF is presented, as determined via the coupled-cluster singles and doubles approach including...
