Gas-phase Chemistry in the Interstellar Medium: The Role of Laboratory Astrochemistry

Frontiers in Astronomy and Space Sciences, 2022
“Who” and how? In this simple question the complexity of the interstellar chemistry is encapsulated. “Who” refers to what molecules are present in the interstellar medium (ISM) and “how” to the mechanisms that led to their formation.

Astrochemistry of Sub-Millimeter Sources in Orion: Studying the Variations of Molecular Tracers with Changing Physical Conditions [PDF]

, 2003
Cornerstone molecules (CO, H_2CO, CH_3OH, HCN, HNC, CN, CS, SO) were observed toward seven sub-millimeter bright sources in the Orion molecular cloud in order to quantify the range of conditions for which individual molecular line tracers provide ...

Is Phenylnitrene a Missing Link in the Formation of Polycyclic Aromatic Nitrogen Heterocycles? [PDF]

Angew Chem Int Ed Engl
A new formation pathway for polycyclic aromatic nitrogen heterocycles (PANHs) has been found. The reaction of phenylnitrene and the propargyl radical leads to quinoline, proving that nitrenes are suitable precursors for nitrogen incorporation mechanisms.
