General subroutines for the calculation of atomic and molecular two-centre integrals

Abstract The Fourier transform method for calculation of atomic and molecular two-centre integrals is programmed in Fortran, using algebraic manipulation techniques. The subroutines can be directly included numerical codes and provide efficient and general methods for the calculation of two-centre integrals for any quantum numbers or geometry.
