Abstract

Molecules of pyrroloquinolines with linear and angular structures have been studied by quantum-chemical methods. The different rules which govern the electronic absorption spectra of these isomers are determined by the different nature of the conjugated structures of the fragments in linear and angular pyrroloquinolines.
