Double substitution in long polyene chains

  • G. F. Kventsel


Conditions are derived for the occurrence of local levels in doubly substituted long polyene chains with and without bond alternation. It is found that substitution on two adjacent chain atoms may give rise to only one local state in the forbidden band. Approximate expressions are derived for the energies of the local states when the perturbed atoms lie far from the end of the chain.
