Abstract
Valence-bond structures with Pauling “3-electron bonds” between pairs of atoms may be constructed for a number of triatomic radicals. Here we shall examine these types of structures for some radicals with either 17 or 19 valence-shell electrons. For these systems, it is necessary to involve the participation 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.
