The electron pairing theory of the structure of conjugated hydrocarbons

Abstract

The electron pairing theory of molecular structure has been extended in its application to conjugated hydrocarbons. Formulae for calculating internuclear distances, force constants and interaction constants are derived. These appear to give rather better results than the already successful molecular orbital theory. The interaction of two conjugated systems is discussed, and it is shown how the conjugating power of a hydrocarbon residue may be correlated with its residual affinity
