Classical Valence Bond Structures and Quinquevalent Nitrogen Atoms,e” structure is sometimes used to represent their electronic structures. Since the 1860s and until the introduction of the Lewis-Langmuir octet theory, nitrogen atoms were often represented with valencies of 3 or 5 in valence-bond structures.

,Pauling “3-Electron Bonds”, 5-Electron 3-Centre Bonding and Some Tetra-Atomic Radicals,icipation in resonance of two Pauling “3-electron bond” structures. The delocalized molecular orbital equivalent of this resonance involves the construction of three 3-centre molecular orbitals to accommodate five electrons; this is described in Section 6-4.
