Abstract

The simplified version given by Heilbronner and others of the P-treatment was used to calculate transition energies and intensities of the π — π* bands in the electronic spectra of 31 azines (aza-benzenes and aza-naphthalenes). A comparison with experimental data results in a better agreement than for the complete treatment.

Zusammenfassung

Nach dem von Heilbronner u. Mitarb. angegebenen vereinfachten P-Verfahre n berechneten wir Übergangsenergien und -intensitäten der π — π*-Elektronenbanden von 31 Azinen (Aza-Benzole und Aza-Naphthaline). Die Übereinstimmung mit dem Experiment ist besser als beim vollständigen Verfahren.

Résumé

Nous utilisons la version simplifiée de la méthode P, d'après Heilbronner et al., pour le calcul des énergies et intensités des transitions électroniques π — π* de 31 azines (aza-benzènes et aza-naphthalènes). L'accord avec l'expérience y est mieux que pour la méthode complète.
