The first steps of interstellar phosphorus chemistry [PDF]
Astronomy & Astrophysics, 2020 Context. Phosphorus-bearing species are essential to the formation of life on Earth, however they have barely been detected in the interstellar medium. In particular, towards star-forming regions only PN and PO have been identified so far. Since only a small number of detections of P-bearing molecules are available, their chemical formation pathways ...

Ab Initio Study of Fine and Hyperfine Interactions in Triplet POH
Molecules, 2022 Phosphorous-containing molecules have a great relevance in prebiotic chemistry in view of the fact that phosphorous is a fundamental constituent of biomolecules, such as RNA, DNA, and ATP.

, 2004 H3+ and the deuterated isotopomers are thought to play an important role in interstellar chemistry. The partition functions of H3+, D2H+ and D3+ are calculated to a temperature of 800 K by explicitly summing the ab initio determined rotation-vibration ...

Gas phase formation of the prebiotic molecule formamide: insights from new quantum computations
, 2015 New insights into the formation of interstellar formamide, a species of great relevance in prebiotic chemistry, are provided by electronic structure and kinetic calculations for the reaction NH2 + H2CO -> NH2CHO + H.

Angewandte Chemie International Edition, EarlyView.By employing dimensionally reduced reaction descriptors, a human–machine collaboration framework for efficient electrochemical nitrate reduction to NH3 electrocatalysts screening is established and drastically shorten the discovery timeframe. A new kinetic model is established in combination with a rotating ring‐disk electrode, unveiling the pivotal ...

Interstellar deuterium chemistry [PDF]
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1981 Abstract An interstellar reaction scheme of the type described by E. Iglesias (Astrophys. J. 218, 697 (1977)) has been extended to include deuterium chemistry and also isomeric forms of some molecules. The role of isomeric forms of the intermediates CNH2 and HCNH+ in the production of interstellar HCN and HNC is considered. The lowest

The chemistry of fluorine-bearing molecules in diffuse and dense interstellar gas clouds
, 2005 We present a theoretical investigation of the chemistry of fluorine-bearing molecules in diffuse and dense interstellar gas clouds. The chemistry of interstellar fluorine is qualitatively different from that of any other element, because - unlike the ...

Clathrate hydrate crystallization
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Clathrate hydrate crystallization has been an area of interest to chemical engineers from the point of view of crystal structure, thermophysical properties, phase equilibria, kinetics, industrial applications, and environmental (climate change) implications.
