Calculation of many-centre two-electron molecular integrals with STO

Abstract A program for the calculation of two-electron molecular integrals between real Slater-type orbitals (STO) is reported.The program is mainly intended for comparison purposes, to analyze and test the results provided by other algorithms. However, it can be used in actual molecular calculations of small systems. The integrals are obtained by means of Gaussian expansions of the STO. Expansions that enable to attain an accuracy of at least ten decimal places in the integrals are included.
