Polarisation der Elektronenbanden von Aromaten 8. Mitteilung: Phenazin, Phenazin‐N‐oxid, Phenazin‐N,N′‐dioxid

Abstract

AbstractDie Elektronen‐ und Polarisationsspektren der Mono‐ und Di‐N‐oxide des Phenazins I und II wurden gemessen und mit Hilfe semiempirischer Modellrechnungen nach Pariser, Parr und Pople zugeordnet. Eine Analyse der Eigenfunktionen der angeregten Zustände ermöglichte es, ein Korrelationsdiagramm der Molekülzustände aufzustellen. Das Korrelationsdiagramm wurde an die berechneten Terme des Phenazins III und Anthracens IV angeschlossen. Die intensivsten Übergänge der Heterocyclen I–III zeigen in Analogie zu Anthracen IV 1La‐, 1Lb‐ und 1Bb‐Charakter. Zusätzlich zu diesen Banden konnten in den Spektren der N‐Oxide schwache Übergänge beobachtet werden, die eng mit der Anregung der NO‐Gruppen verbunden sind. Die π‐Elektronendichten und π‐Bindungsordnungen von I – III werden diskutiert.
