Woodward-Hoffman rules state that pericyclic reactions can only happen if the symmetries of these objects are the same in both the reactants and products. The LCAO approximation allows one to diagram these objects; in those diagrams, an asterisk denotes the "antibonding" type. They are mathematically expressed in the (*) Hartree-Fock equation, and 
Woodward-Hoffman rules state that pericyclic reactions can only happen if the symmetries of these objects are the same in both the reactants and products. The LCAO approximation allows one to diagram these objects; in those diagrams, an asterisk denotes the "antibonding" type. They are mathematically expressed in the (*) Hartree-Fock equation, and are denoted by the Greek letters phi, delta, pi, and omega, which correspond to the f, d, p, and s atomic orbitals. For 10 points, name these regions in which electrons are likely to be found when shared between two atoms.
