Abstract The absorption and fluorescence of three isomeric distyrylbenzenes are investigated as function of temperature. From the fluorescence decay times and fluorescence quantum yields two classes of oligostyrylarenes can be distinguished. A decisive criterion for this classification is, whether the first excited singlet state S1 belongs to an allowed or forbidden transition S0→S1.

Recent Developments

A lifetimes technique that is readily applicable to neutral and singly ionised atoms of a wide range of elements, including the highly refractory elements, is reviewed. With this technique an atomic vapour of the element under study is generated by cathodic sputtering in a low pressure rare-gas discharge and fluorescence decay signals emitted by the vapour following pulsed laser excitation are recorded directly in a fast transient digitiser. Theoretical expressions are presented for the form of the time-resolved fluor~scence signal appropriate to the collisional environment of a rare-gas sputtering discharge. A summary is given of the atomic systems studied to date using this technique, and some new results for Sm and Ba are compared with recently reported results for these elements.

The absorption spectra of the 3 isomeric aza- and the 4 isomeric azinium-anthracenes 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 aziniumgroup, respectively. In the case of acridine, acridinium, benzo[g]quinolinium and benzo[f]- isoquinolinium the S0 → S2-transition is observable. The spectra of benzo[g]quinoline, benzo[f]- isoquinoline and acridizinium are similar to those of anthracene
