Life Cycle Assessment in the Fruit Sector,-rich molecules that involve 4-electron 3-centre and 6-electron 4-centre bonding units. To do this, we may use any of three alternative methods. In this Chapter, we shall discuss one of them. It involves the spin-pairing of the unpaired-electron of . · . with the unpaired electron of either an atom.

To do this, we must delocalize one or more lone-pair electrons into . two-centre bonding orbitals . two-centre antibonding orbitals, both types of orbitals being vacant in the standard Lewis structures.

Much, if not all of this material could be familiar to many readers. For fuller treatments, the reader should consult some of the numerous standard texts on quantum mechanics and valence.

Some Dimers of Triatomic Radicals with 17 and 19 Valence-Shell Electrons, illustrate aspects of qualitative valence-bond and molecular orbital theory for electron-rich polyatomic molecules, and interconnections between these theories can be demonstrated. Dinitrogen tetroxide is a molecule . that may be used for these purposes, and here we shall give primary consideration to its electronic structure and bond properties.

Life Cycle Assessment (LCA) — Quo vadis?Although it is not well-recognized, transition metal complexes exist for which Pauling “3-electron bond” theory is relevant. To illustrate this theory, consideration will be given to descriptions of the electronic structures for a number of octahedral complexes.
