The Effect of an Inert Solid Reservoir on Molecular Abundances in Dense Interstellar Clouds

open access: yesOpen Astronomy, 2012
The question, what is the role of freeze-out of chemical species in determining the molecular abundances in the interstellar gas is a matter of debate.

The largest oxigen bearing organic molecule repository

open access: yes, 2007
We present the first detection of complex aldehydes and isomers in three typical molecular clouds located within 200pc of the center of our Galaxy. We find very large abundances of these complex organic molecules (COMs) in the central molecular zone ...

Carbon isotope fractionation and depletion in TMC1

open access: yes, 2012
12C/13C isotopologue abundance anomalies have long been predicted for gas-phase chemistry in molecules other than CO and have recently been observed in the Taurus molecular cloud in several species hosting more than one carbon atom, i.e.

Reactivity of hydrated hydroxide anion cluster OH(H$_{2}$O)$_{n}^{-}$ with H and Rb: an ab initio study

open access: yes, 2019
We present a theoretical investigation of the hydrated hydroxide anion clusters OH(H$_{2}$O)$_{n}^{-}$ and of the collisional complexes H-OH(H$_{2}$O)$_{n}^{-}$ and Rb-OH(H$_{2}$O)$_{n}^{-}$ (with n$=1-4$).

The Case of H$_2$C$_3$O Isomers, Revisited: Solving the Mystery of the Missing Propadienone

open access: yes, 2019
To date, two isomers of H$_2$C$_3$O have been detected, namely, propynal (HCCCHO) and cylclopropenone (c-H$_2$C$_3$O). A third, propadienone (CH$_2$CCO), has thus far eluded observers despite the fact that it is the lowest in energy of the three.

Electron-Induced Chemistry in the Condensed Phase

open access: yesAtoms, 2019
Electron–molecule interactions have been studied for a long time. Most of these studies have in the past been limited to the gas phase. In the condensed-phase processes that have recently attracted attention from academia as well as industry, a ...

Infrared Spectroscopic and Physical Properties of Methanol Ices—Reconciling the Conflicting Published Band Strengths of an Important Interstellar Solid

open access: yesThe Astrophysical Journal
Infrared spectroscopic observations have established the presence of solid methanol (CH _3 OH) in the interstellar medium and in solar system ices, but the abundance of frozen CH _3 OH cannot be deduced without accurate band strengths, optical constants,
