Pi bonds are crucial for understanding molecular structure and reactivity. Unlike sigma bonds, formed by head-on orbital overlap and constitute the first bond between two atoms, pi bonds arise ...

Simplified Hückel Molecular Orbital Theory (SHMO) allows us to create π-molecular orbitals for planar systems. It is qualitatively accurate and often all one needs to interpret π-systems in physical ...

Atoms of a molecule (gray) are shown, with their accompanying pi orbitals (red). As the distance between electrodes is decreased, the pi orbitals can interact with the electron orbitals contained ...

In the molecular orbital theory of valency the electrons are assigned to the whole molecule rather than to atoms or to other localized parts. While the method has advantages in dealing with the ...
