Computation of molecular integrals over Slater-type orbitals. III. Calculation of multicenter nuclear-attraction integrals using recurrence relations for overlap integrals
Özet
Using recurrence relations for basic overlap integrals two- and three-center nuclear-attraction integrals are calculated for extremely large quantum numbers. The accuracy of the results is quite high for the principal quantum numbers of Slater functions and for the arbitrary values of internuclear distances and screening constants of atomic orbitals.
