A KINETIC DATABASE FOR ASTROCHEMISTRY (KIDA) [PDF]
Astrophysical Journal, Supplement Series, 2012 We present a novel chemical database for gas-phase astrochemistry. Named the KInetic Database for Astrochemistry (KIDA), this database consists of gas-phase reactions with rate coefficients and uncertainties that will be vetted to the greatest extent possible.

The UMIST database for astrochemistry 2012 [PDF]
Astronomy & Astrophysics, 2012 We present the fifth release of the UMIST Database for Astrochemistry (UDfA). The new reaction network contains 6173 gas-phase reactions, involving 467 species, 47 of which are new to this release. We have updated rate coefficients across all reaction types. We have included 1171 new anion reactions and updated and reviewed all photorates.

Exploring outer space biophysical phenomena via SpaceLID [PDF]
Scientific Reports, 2023 Extensive investigations in outer space have revealed not only how life adapts to the space environment, but also that interesting biophysical phenomena occur. These phenomena affect human health and other life forms (animals, plants, bacteria, and fungi)

Reaction Kinetics in a Tight Spot [PDF]
Small 5 (2005) 502, 2005 The standard analysis of reaction networks based on deterministic rate equations fails in confined geometries, commonly encountered in fields such as astrochemistry, thin film growth and cell biology. In these systems the small reactant population implies anomalous behavior of reaction rates, which can be accounted for only by following the full ...

Anatomy of Orion Molecular Clouds—The Astrochemistry Perspective/Approach
Frontiers in Astronomy and Space Sciences, 2021 The Orion molecular cloud (OMC) complex is the nearest and perhaps the best-studied giant molecular cloud complex within which low-mass and massive star formation occur. A variety of molecular species, from diatomic molecules to complex organic molecules

Ab initio Calculations for Astrochemistry [PDF]
arXivComputational chemistry plays a relevant role in many astrochemical research fields, either by complementing experimental measurements or by deriving parameters difficult to be reproduced by laboratories. While the role of computational spectroscopy in assisting new observations in space is described, the core of the chapter is the investigation of the
