[The Interpretation of Absorption Spectra of Aza- and Azinium-Substituted Anthracenes]

The absorption spectra of the 3 isomeric aza- and the 4 isomeric azinium-anthraoenes are discussed on the basis of the absorption anisotropy, the oscillator strenght and the fluorescence decay times. The influence of endocyclic substitution depends on the position of the aza- and azininrngroup, respectively. In the case of acridine, acridinium» benzo[g]quinolinium and benzoff]isoquinolinium the So -> Sa-transition is observable. The spectra of benzo[g]quinoline, benzo[f)* isoquinoline and acridizinium are similar to those of anthracene.
