Techniques for computing the multicenter integrals required for molecular calculations for orbitals for which the radial factors are given numerically are described. The methods make extensive use of a numerical algorithm for computing spherical Bessel transforms. The feasibility of using these methods is demonstrated by applying them to SCF calculations for the methane molecule. © 1993 John Wiley & Sons, Inc.
