Astrochemical relevance of VUV ionization of large PAH cations
Context. As part of interstellar dust, polycyclic aromatic hydrocarbons (PAHs) are processed
by an interaction with vacuum ultraviolet (VUV) photons emitted by hot stars. This interaction …

Formation of the acenaphthylene cation as a common C 2 H 2-loss fragment in dissociative ionization of the PAH isomers anthracene and phenanthrene
Polycyclic aromatic hydrocarbons (PAHs) are thought to be a major constituent of
astrophysical environments, being the carriers of the ubiquitous aromatic infrared bands …

Laboratory photochemistry of pyrene clusters: An efficient way to form large PAHs
In this work, we study the photodissociation processes of small PAH clusters (eg, pyrene
clusters). The experiments are carried out using a quadrupole ion trap in combination with …

Polyacenes and diffuse interstellar bands
A Omont, HF Bettinger, C Tönshoff - Astronomy & Astrophysics, 2019 - aanda.org
The identification of the carriers of the diffuse interstellar bands (DIBs) remains to be
established, with the exception of five bands attributed to C, although it is generally agreed …
