Conclusions and recommendations,his is often true. However, for some simple systems, there exists an elementary valence-bond counterpart for each molecular orbital description of the excited state. To demonstrate this point, we shall give consideration here to a few types of electronic excitations.

Maria Laura Parisi,Riccardo Basosie” 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.

Atomic Orbitals, Electron Spin, Linear Combinations,s book. In general, we shall state only the main results, without any derivation of them. 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.

Valence-Bond Structures for some Diatomic and related Molecules,s. To do this, initially we shall use their molecular orbital configurations together with the prototype valence-bond structures of Table 3-2. Green and Linnett. adopted this approach to the construction of valence-bond structures, and they have described many of the valence-bond structures that we

As examples, we shall consider the Cu(II)-carboxylate, Cu(II)-chloro and Cu(II)-hydroxo dimers (Cu. (RCO.)., L. with. = 0 or 2, and Cu.X. with X = Cl or OH. Their geometries are displayed in Figure 8-1. Initially we shall no
