Recently it has been studied by several authors to calculate the three-center integrals in molecular quantum mechanics. We have offered also a general method to calculate those three-center integrals of one electron, and noted the possibility of computing such integrals for two electrons.
In this calculation we have used the formulae given by Hirschfelder and the charge distribution function by Ruedenberg.
