描述This book provides qualitative molecular orbital and valence-bond descriptions of the electronic structures for electron-rich molecules, with strong emphasis given to the valence-bond approach. Electron-rich molecules form an extremely large class of molecules, and the results of quantum mechanical studies from different laboratories indicate that qualitative valence-bond descriptions for many of these molecules are incomplete in so far as they usually omit "long-bond" Lewis structures from elementary descriptions of bonding. For example, the usual representation for the electronic structure of the ground-state for 03 involves resonance between the (+1 o and Until standard Lewis structures ~ ~ (-I . b:‘" ~d· . . . . , recently, any contribution to resonance of the "long-bond" (or spin-paired o ?? / ?? ,. . has been largely ignored. diradica~ Lewis structure However, it :0 . 0. . e-. . . . . ______ " has now been calculated to be a very important structure. For the ground-states of numerous other systems, calculations also indicate that "long-bond" structures are more important than is usually supposed, and therefore they should frequently be included in qualitative valence-bond des

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 in particular, interconnections between these theories can be demonstrated. Dinitrogen tetroxide is a molecule . that may be used for these purposes, and we shall give primary con

,Pauling “3-Electron Bonds” and “Increased Valence” Theory for N2O4,electron of one NO. moiety with the odd-electron of the other moiety, to obtain the Lewis octet structures (3)–(7) of Section 7-1 for N.O.. In Section 6-1, we have also indicated that resonance between the NO. Lewis structures (1) and (2) may be summarized by using the Pauling “3-electron bond” stru

,Pauling “3-Electron Bonds” and “Increased-Valence” Structures,h 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 . or a s
