Abstract
Characteristic charge-transfer absorption bands of some heterocyclic nitrones as electron donor with tetracyanoethylene, 2,3-dichloro-5,6-dicyanobenzoquinone and chloranil as electron acceptor have been measured in methylene chloride solution. The stoichiometry, apparent formation constants and transition energies of the charge-transfer complexes formed as well as the effect of solvent and the stability of these complexes are discussed.
Zusammenfassung
Die charakteristischen Charge-Transfer Absorptionen einiger heterocyclischer Nitrone als Elektron-Donor mit Tetracyanoethylen, 2,3-Dichlor-5,6-dicyanobenzochinon bzw. Chloranil als Elektron-Acceptor wurden in Methylenchlorid als Lösungsmittel gemessen. Stöchiometrie, effektive Bildungskonstanten und Einfluß des Lösungsmittels auf die Stabilität der Komplexe werden diskutiert.
