For the 1st time the self-discipline of contemporary inorganic chemistry has been systematized in response to a plan built by means of a council of editorial advisors and specialists, between them 3 Nobel laureates (E. O. Fischer, H. Taube and G. Wilkinson). instead of generating a set of unrelated assessment articles, the sequence creates a framework which displays the artistic strength of this clinical self-discipline.

The Kekul6 description of benzene, as expressed in the classical VB form, appears to be much closer to reality than is a description in terms of delocalized molecular orbitals, and it provides a clear picture of the behavior of correlated electrons in this molecule. The special properties of benzene arise fundamentally from the mode of coupling of the electron spins around the carbon ring framework. Except for small but crucial distortions of the orbitals, the spin-coupled and classical VB descriptions of this molecule are very similar.
