Hückel Valence Bond Theory of Stereoselection

1982
Why should we pursue an understanding of aromaticity and antiaromaticity on the basis of HVB theory? The first and most important reason is that HVB theory is equivalent to the theory which is the foundation of most present day concepts of chemistry: HMO theory with neglect of overlap.

Ab Initio Modern Valence Bond Theory

1999
We concentrate in the present account on certain recent developments linked to extensions of spin-coupled theory. In particular, we describe the so-called SCVB* strategy, which employs optimised virtual orbitals to reduce still further the number of nonorthogonal configurations required in accurate calculations of ground and excited state potential ...

Valence Bond Theory in Heterocyclic Chemistry

2014
This chapter deals with the application of valence bond theory in heterocyclic chemistry. A short introduction to the different valence bond methods is given, followed by illustrative results obtained by valence bond calculations. The illustrations show the applicability of the valence bond theory to obtain detailed information on the electronic ...

Valence bond theory in coordination chemistry

Journal of Chemical Education, 1962
The author disagrees that the valence bond theory has suffered a rapid fall from favor, and that there has been a consequent rise in esteem of the molecular orbit and crystal field theories.
