Bond length alternation in s-indacene

T Nakajima, T Saijo, H Yamaguchi - Tetrahedron, 1964 - Elsevier
Using a modification of the Hückel MO theory, it is shown that in the s-indacene molecule
the peripheral CC bonds alternate considerably in length, and the skew structure (C 2h ) is …

A Formal relation between valence bond and molecular orbital theory

JAR Coope - Chemical Physics Letters, 1967 - Elsevier
The simple valence bond method is formulated in terms of fermion spin waves. For linear
chains, rings containing 4n+2 atoms, and polyacenes, we obtain a close formal …
