Using a distance-dependent Heisenberg Hamiltonian extracted from calculations on ethylene, the bond alternation (which solid state physicists call dimerization) of polyacetylene is studied through either exact diagonalization for finite cyclic and linear polyenes, or modified coupled cluster treatme
## Abstract A crystal chemical approach to superconductivity based upon a bond-valence sum analysis of inorganic compounds is extended by an analysis of local bond-valence distribution. The notions of stoichiometric and structural valence together with Paulingβs rule of equal distribution of valenc
