Abstract
A one‐range expansion of the 0s‐STO—previously reported by us—is employed to derive explicit expressions for the elements of auxiliary matrices—appearing in the calculation of one‐ and two‐electron multicenter integrals with STOS—in the form of infinite series. Then, we are able to perform the formal summation of the series giving both closed expressions for these elements and several relations between them. A computational algorithm based on these formal developments is proposed and its numerical behavior is analyzed.Keywords
