Web13 nov. 2006 · Hückel's “Zürich habilitation thesis” dealt with what has become famous as the Debye–Hückel theory of strong electrolytes. 9 Hückel was a traveling postdoc in London, Copenhagen (with N. Bohr) and Leipzig (with W. Heisenberg and F. Hund). In 1930 he became a lecturer in Chemical Physics at the Technische Hochschule Stuttgart.

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… http://reports.ias.ac.in/report/14114/huckel-theory-and-band-theory-computational-approach

WebThe correspondence between method A and the simple Huckel method can now be demonstrated by showing the one-to-one relation between Huckel 12, values obtained empirically and the h, calculated by [32] from the valence-state energy data. The only difficulty in such an analysis is the choice of appropriate Huckel h, to be used.
