The role of highly vibrationally excited H-2 initiating the nitrogen chemistry Quantum study and 3 sigma – detection of NH emission in the Orion Bar PDR
Authors: Goicoechea, Javier R.; Roncero, Octavio Journal: ASTRONOMY & ASTROPHYSICS Publication date: 2022/08/31 DOI: 10.1051/0004-6361/202243884 Abstract: The formation of hydrides by gas-phase reactions between H-2 and a heavy element atom is a very selective process. Reactions with ground-state neutral carbon, oxygen, nitrogen, and sulfur atoms are very endoergic and have high energy barriers because the [...]
