We present a first-principles MD (FPMD) study of the interaction of low-energy, positively charged carbon (C(+)) projectiles with amorphous solid water clusters at 30 K. Reactions involving the carbon ion at an initial energy of 11 and 1.7 eV with a 30-molecule cluster have been investigated. Simulations indicate that the neutral isoformyl radical, COH(•), and carbon monoxide, CO, are the dominant products of these reactions. All of these reactions are accompanied by the transfer of a proton…

Water radiolysis by low-energy carbon projectiles from first-principles molecular dynamics

It is found that the maximum spatial production of radiolysis products, not only occurs at low velocities, but also well below the maximum of energy deposition, reaching one H every 5 Å at the lowest speed studied (1 Bohr/fs).

Formation of formaldehyde through methanol-ice-mantle (CH3OH)10 bombardment by OH+ cation

Context. Formaldehyde H2CO was the first organic polyatomic molecule discovered in the interstellar medium to have been detected in a variety of sources. However, pathways to synthesize this molecule

Basic protocols are proposed for identifying the degree to which DFT methods are able to reproduce experimental or higher level theoretical results for the fundamental interactions upon which ice mantle chemistry depends, including both reactive interactions and non-reactive scaffolding interactions.



Organic synthesis in the interstellar medium by low-energy carbon irradiation.

A first principles molecular dynamics study of the interaction of low-energy neutral carbon projectiles with amorphous solid water clusters at 30 K finds that the formation of hydroxymethylene dominates at the higher energy, while at the lower energy water fragmentation is not favorable, thus leading to theformation of weakly bound carbon-water complexes.

Collision complex formation in the reaction of C+ with H2O

A crossed beam study of the title reaction at collision energies of 0.62 and 2.14 eV demonstrates that the production of mass 29 ions, either HCO+ or COH+, occurs through the formation of a transient

Irradiation of Water Ices by 2 keV Carbon Ions

In this paper, we report on the results of experimental studies of the irradiation of pure water ices using 2 keV 13C+ and 13C2+ ions. Studies have been carried out at two temperatures (30 and 90 K)

First-principles molecular dynamics simulations of the interaction of ionic projectiles with liquid water and ice

We first present results of first‐principles molecular dynamics simulations of the passage of Carbon projectiles through water in the liquid state in the adiabatic regime, where the electrons are

The "non-reaction" of ground-state triplet carbon atoms with water revisited.

It is found that triplet carbon atoms indeed do not react with water, despite their high initial energy, and the proposed formation of aldoses in extraterrestrial environments can therefore only derive from "hot" carbon atoms or through photoreactions.

Laboratory measurements of ion-molecule reactions pertaining to interstellar hydrocarbon synthesis

Measurements on a variety of three-body association reactions between hydrocarbon ions and molecular hydrogen in the presence of helium have been undertaken. The rate coefficients of most of the

The role of the excited electronic states in the C+ + H2O reaction.

The analysis suggests that the first excited state could play an important role in the generation of the formyl isomer, which has been detected in crossed beam experiments and could not be explained in quasiclassical trajectory computations.

Low energy 13C+ and 13C2+ ion irradiation of water ice.

The results of the first experimental study of the irradiation of low temperature water ice using low energy 13C+ and 13C2+ ions were reported, with the product yield and growth rate observed to be highly dependent on both the sample temperature and ion charge state.

Reactions of 1S, 1D, and 3P carbon atoms with water. Oxygen abstraction and intermolecular formaldehyde generation mechanisms; An MCSCF study

Reactions of singlet and triplet carbon atoms with water are explored theoretically using CASSCF–MCQDPT2, CCSD, and DFT methodologies. The 1S carbons are found to be unreactive. Depending on the
