Abstract

Coulomb correlations between an extended π subsystem and localized π′ dimers are found for the 2¹A and 1³B states of polydiacetylene (PDA) fragments. In contrast to the red shift and splitting found previously for dipole-allowed ¹B excitations, π-π′ coupling blue shifts 2¹A and 1³B but hardly affects the 1³B fine structure constants. Pseudocovalent contributions to correlated states rationalize these results.
