Near HF energies can be obtained with small GTO basis sets and optimized functions in the centers of chemical bonds. Energy differences, force constants and charge distributions remain almost unchanged, if the number of gaussian functions representing the cusp at the nuclei is reduced drastically. Three examples are discussed in detail: H2. LiH and Li2.
