If the overlap is neglected, as in simple Hückel theory, the splitting would be symmetric.

Web13 nov. 2006 · Hückel's MO theory was extended successfully by various colleagues, sometimes without reference to Hückel's fundamental work. This holds especially for the English school of Lennard‐Jones, Coulson, and Longuet‐Higgins. These authors preferred the name MO‐LCAO to HMO.

The Hückel method or Hückel molecular orbital theory, proposed by Erich Hückel in 1930, is a simple method for calculating molecular orbitals as linear combinations of atomic orbitals. The theory predicts the molecular orbitals for π-electrons in π-delocalized molecules, such as ethylene, benzene, butadiene, and pyridine. It provides the theoretical basis for Hückel's rule that cyclic, planar molecules or ions with π-electrons are aromatic. It was later extended to conjugated molec… flashdance plotWeb2 dagen geleden · Eric Huckel, a German Physicist and Chemist, in the year 1931 proposed a theory that helped us determine the presence of Aromatic properties in a Planar Ring Molecule.
