Hückel theory, which forms the conceptual basis of the semiempirical methods (NNDO, CNDO, et cetera), is the focus of two complete chapters in Peterson's Quantum Chemistry textbook. This Journal has featured excellent material vis-a-vis computer programs for educators that complement this textbook treatment, including VBA macros for diagonalizing the Hückel matrix and tools for visualizing the resultant LCAO molecular orbitals. Hartree-Fock (HF) theory, the foundation of all WF-based methods, accounts for the majority of Szabo and Ostlund's Modern Quantum Chemistry and a substantial part of Levine's textbook. Freitag et al published educational software that explicates the Hartree-Fock-Roothaan equations in a procedural fashion for a few simple two-electron systems, H2, HeH + , and He2 2+ . Similarly, basis sets, a feature of essentially all programs for conveniently representing orbitals, are also addressed in many texts and several pedagogic exercises have been published detailing the properties of gaussian-and Slater-type functions. These exercises provide a hands-on feel for performing calculations that cannot be obtained through a traditional textbook.
