Organizing Organic Reactions: The Importance of Antibonding Orbitals  David E. Lewis
It is proposed that unoccupied molecular orbitals arbitrate much organic reactivity, and that they provide the basis for a reactivity-based system for organizing organic reactions. Such a system is proposed for organizing organic reactions according to principles of reactivity, and the system is discussed with examples of the frontier orbitals involved.

Pericyclic Reactions: FMO Approach-Abstract of Issue 9904M  Albert W. M. Lee, C. T. So, C. L. Chan, and Y. K. Wu
Pericyclic Reactions: FMO Approach is a program for Macintosh computers in which the frontier molecular orbital approaches to electrocyclic and cycloaddition reactions are animated. The bonding or antibonding interactions of the frontier molecular orbital(s) determine whether the reactions are thermally or photochemically allowed or forbidden.

Models to illustrate orbital symmetry effects in organic reactions  Brown, Peter
From a pedagogic point of view, conservation of orbital symmetry is easily assimilated by students with a rudimentary knowledge of simple MO theory and of symmetry. The author has found in teaching over the past three years at both graduate and undergraduate levels that use of a simple set of orbital models as described in this article has enormous advantages as a visual aid in the construction and assignment of symmetry elements to the appropriate semi-localized Huckel-type MOs and in following their stereo chemical fate in concerned reactions.
