- Sigma-pi_and_equivalent-orbital_models abstract "The σ-π model and equivalent-orbital model refer to two possible representations of molecules in valence bond theory. The σ-π model differentiates bonds and lone pairs of σ symmetry from those of π symmetry, while the equivalent-orbital model hybridizes them. The σ-π treatment takes into account molecular symmetry and is better suited to interpretation of aromatic molecules (Hückel's rule) and photoelectron spectra, although computational calculations of certain molecules tend to optimize better under the equivalent-orbital treatment. The total wave functions of the two representations are mathematically equivalent and different localization procedures yield either of the two. In a 1996 review, Kenneth B. Wiberg concluded that \"although a conclusive statement cannot be made on the basis of the currently available information, it seems likely that we can continue to consider the σ/π and bent-bond descriptions of ethylene to be equivalent. Ian Fleming goes further in a 2010 textbook, noting that \"the overall distribution of electrons [...] is exactly the same\" in the two models.".
