Computation of molecular integrals over Slater-type orbitals. IV. Calculation of multicenter electron-repulsion integrals using recurrence relations for overlap integrals
Özet
Using formulas given by one of the authors [I.I. Guseinov, J. Mel. Struct. (Theochem) 417 (1997) 117], the multicenter electron-repulsion integrals with the arbitrary location and screening constants of Slater-type orbitals (STOs) are calculated for extremely large quantum numbers. Accuracy of the results is quite high for quantum numbers n, l and m of STOs. (C) 2000 Elsevier Science B.V. All rights reserved.
