Hückel method
From Wikipedia, the free encyclopedia
The Hückel method, proposed by Erich Hückel in 1930, is a very simple LCAO MO Method for the determination of energies of molecular orbitals of pi electrons in conjugated hydrocarbon systems, such as ethene, benzene and butadiene. It is the theoretical basis for the Hückel's rule. It was later extended to conjugated molecules such as pyridine, pyrole and furan that contain atoms other than carbon, known in this context as heteroatoms.
It is a very powerful educational tool and details appear in many chemistry text books.
