Numerical Evaluation of Two–Center Overlap Integrals Over Slater–Type Orbitals and Convergence Properties
Motivation. Among the molecular integrals, the two-center overlap integrals play a major role in any accurate molecular structure calculation. They are central to the calculation of multicenter overlap integrals when using the series expansion formulae for Slater type functions about a new center. Consequently, these integrals require an accurate and fast numerical evaluation. Recently, we show...
متن کاملSymbolic tabulation of overlap integrals over Slater orbitals
We have used computer algebra CA to tabulate closed expressions for over lap integrals of Slater orbitals with principal quantum numbers to con taining symbolic molecular parameters Also we have constructed precise closed expressions for a range of overlap integrals de ned by higher quantum numbers and numerical bond lengths and or screening constants Numerical values obtained from both sets of...
متن کاملTwo - Electron Repulsion Integrals Over Gaussian s Functions
We present an efficient scheme to evaluate the [O](m) integrals that arise in many ab initio quantum chemical two-electron integral algorithms. The total number of floating-point operations (FLOPS) required by the scheme has been carefully minimized, both for cases where multipole expansions of the integrals are admissable and for cases where this is not so. The algorithm is based on the use of...
متن کاملEvaluation of Two-Center, Two-Electron Integrals.
We present a new analytic treatment of two-electron integrals over two-center integrals including correlation (interelectronic distance) explicitly in the wave function. All the integrals needed for the evaluation of the matrix elements of any diatomic two-electron molecule are obtained as analytic recursion expressions. As an application of this method in molecular physics, we calculate the va...
متن کاملRapid evaluation of two-center two-electron integrals
We present optimal formulae for two-center two-electron replusion integrals (ERIs) over Cartesian Gaussian basis functions. Floating-point operations (flop) counts reveal that two-center ERIs are often an order of magnitude cheaper than their four-center analogues. c © 2000 John Wiley & Sons, Inc.
