Benzene and Its Ions

It remains only to draw together the main conclusions from this work. They may be stated very briefly as follows  

The few examples in Sect.6 speak for themselves they show clearly that, in spite of magnificent advances in computational chemistry , the use of a handful of VB structures can provide a decent alternative to calculations employing many millions of Slater determinants. In the much quoted words of C. A. Coulson, they offer primitive patterns of understanding that are at the heart of chemistry and not easily found in other ways.
