Abstract
The effects on the absorption spectra of polyphenylenes of charge-conjugation symmetry breaking are studied within the framework of a recently introduced microscopic model. Breaking of this symmetry is shown to result in the appearance of a fourth distinct absorption band in the spectra of derivatized and atomically bridged polyphenylenes, providing further direct experimental information on the intramonomer contribution to the effective electron-hole interaction.Keywords
