Despite the generally hostile nature of the environments involved, chemistry does occur in
space. Molecules are seen in environments that span a wide range of physical and chemical …

Polycyclic aromatic hydrocarbon (PAH) molecules are abundant and widespread throughout
the Universe, as revealed by their distinctive set of emission bands at 3.3, 6.2, 7.7, 8.6, 11.3 …

Polycyclic aromatic hydrocarbons and polycyclic aromatic nitrogen heterocycles are thought
to be widespread throughout the universe, because these classes of molecules are probably …

Large polycyclic aromatic hydrocarbon (PAH) molecules carry the infrared (IR) emission
features that dominate the spectra of most galactic and extragalactic sources. This review …

Molecular absorption and emission bands dominate the visible, infrared, and submillimeter
spectra of most objects with associated gas. These observations reveal a surprisingly rich …

The recent high-pressure synthesis of pentazolates and the subsequent stabilization of the
aromatic [N5]− anion at atmospheric pressure have had an immense impact on nitrogen …

The astronomical emission features, formerly known as the unidentified infrared bands, are
now commonly ascribed to polycyclic aromatic hydrocarbons (PAHs). The laboratory …

Abstract Version 3.00 of the library of computed spectra in the NASA Ames PAH IR
Spectroscopic Database (PAHdb) is described. Version 3.00 introduces the use of multiple …

A critical review of the very long-standing problem of the diffuse interstellar bands is
presented with emphasis on spectroscopic aspects of observational, modelling and …

We introduce a new 1D coupled Radiative/Convective-Photochemical-Microphysical model
for a planetary atmosphere and apply it to Titan. The model incorporates detailed radiation …
