Thus, the π system is forced by the σ framework to adopt a regular geometry rather than an alternated one of Kekulé type. The quantum mechanical resonance energy (QMRE), stabilization directly due to the mixing of Kekulé structu

Benzenoid hydrocarbons in space: The evidence and implications,xcited benzenoid hydrocarbons referred to as polycyclic aromatic hydrocarbons (PAHs). The most intense emitters contain between 20 to 50 carbon atoms, although larger species also contribute to the emission. This assignment is based on a rough resemblance of the interstellar emission spectra to the
