Abstract
The photoionization efficiency curves of phenanthrene, anthracene, flu oranthene, pyrene and triphenylene have been measured by VUV photoioni zation. All spectra show a similar resonance peak at around 17 eV. Thi s phenomenon can be explained as being due to autoionization via a gia nt plasmon resonance. Autoionization has a negligible contribution to fragmentation processes which occur in the same energy range.
