Structure‐Resonance Theory. A Review of Applications to π ‐Hydrocarbon Systems

Studies of structure‐resonance theory applied to π‐hydrocarbon systems are reviewed. The theory leads to quickly obtainable quantitative predictions of bond orders, charge distributions, and relative stabilities of ground state species or reaction intermediates. Numerical results correlate precisely with experimental properties, and with results of LCAO‐MO‐SCF calculations.
