The low band gap polyconjugated aromatic material PITN (see figure, left) is shown, on the basis of te results of Raman spectroscopy, to in fact have the quinoid structure in its electronic ground state. This is the first demonstration that these technologically interesting materials adopt the quinoid structure.
