The calculation of molecular integrals is extremely important for applications to such diverse areas as statistical mechanics and quantum chemistry. A careful derivation of a method for calculating primitive Gaussian integrals originally proposed by Obara and Saika is presented. The basic recursion

β¦ Synopsis
In this paper we will consider some of the methods involved in carrying out density functional calculations within the framework of localised basis sets, specifically those of Gaussian type orbitals. Particular emphasis is placed on the methods used in the AIMPRO (Ab Initio Modelling PROgram) code, but mention is made of a number of developments and strategies used in other programs.
