Journal ArticleDOI
Interstellar Polycyclic Aromatic Hydrocarbon Molecules
TL;DR: In this paper, a review of the observed mid-IR spectral properties of polycyclic aromatic hydrocarbons (PAHs) is presented, emphasizing the contribution of these species to photoelectric heating and the ionization balance of the interstellar gas and to the formation of small hydrocarbon radicals and carbon chains.

Infrared Emission from Interstellar Dust. II. The Diffuse Interstellar Medium
Aigen Li,Bruce T. Draine +1 more
TL;DR: In this article, the authors present a quantitative model for the infrared emission from dust in the diffuse interstellar medium, which consists of a mixture of amorphous silicate grains and carbonaceous grains, each with a wide size distribution ranging from molecules containing tens of atoms to large grains 1 μm in diameter.
Journal ArticleDOI
The molecular universe
TL;DR: In this paper, a review of molecular observations in various spectral windows and summarizes the chemical and physical processes involved in the formation and evolution of interstellar molecules is presented, focusing on the characteristics of complex polycyclic aromatic hydrocarbon molecules and fullerenes.
Journal ArticleDOI
Gas-phase infrared multiple photon dissociation spectroscopy of mass-selected molecular ions
TL;DR: In this paper, the authors present an overview of recent work on the infrared spectroscopy of mass-selected gas-phase molecular ions, where the ions are stored and isolated in a quadrupole ion trap where they are investigated with infrared multiple photon dissociation using a free electron laser (FEL).

TL;DR: In this paper, a power-law distribution of small a-C grains and log-normal distributions of large a-SilFe and aC(:H) grains are used to explore dust evolution in the interstellar medium, and it is shown that mantle accretion in molecular clouds and UV photo-processing in photodominated regions are likely the major drivers of dust evolution.
