Abstract

Context. Polycyclic aromatic hydrocarbons (PAHs) are known today to be one of the carriers of the ubiquitous aromatic infrared (IR) bands. The IR spectra of many astrophysical objects show IR emission features derived from PAH molecules of different size. Space-based observations have shown that these IR emission features are omnipresent and can be found in most objects. However, some of the characteristics of the emitting population remain unclear. The emission bands show details that cannot be explained so far. These unidentified IR features require more laboratory and observational investigations.
