Hückel or Huckel may refer to:
*
Erich Hückel (1896-1980), German physicist and chemist
**
Debye–Hückel equation
The chemists Peter Debye and Erich Hückel noticed that solutions that contain ionic solutes do not behave ideally even at very low concentrations. So, while the concentration of the solutes is fundamental to the calculation of the dynamics of a ...
(named after Peter Debye and Erich Hückel), in chemistry, a method of calculating activity coefficients
**
Hückel method
The Hückel method or Hückel molecular orbital theory, proposed by Erich Hückel in 1930, is a simple LCAO MO Method, method for calculating molecular orbitals as linear combinations of atomic orbitals. The theory predicts the molecular orbitals f ...
(named after Erich Hückel), a method for the determination of energies of molecular orbitals
***
Extended Hückel method, considers also sigma orbitals (whereas the original Hückel method only considers pi orbitals)
**
Hückel's rule
In organic chemistry, Hückel's rule predicts that a planar ring molecule will have aromatic properties if it has 4''n'' + 2 π electrons, where ''n'' is a non-negative integer. The quantum mechanical basis for its formulation was ...
(named after Erich Hückel), a method of determining aromaticity in organic molecules
* (1895-1973), German chemist
* (born 1936), German diplomat, Ambassador of the GDR in Chad
