The reactive open-shell species play a very important role in the radiation-induced
molecular evolution occurring in the cold areas of space and presumably leading to the …

Acetylene, among the multitude of organic molecules discovered in space, plays a distinct
role in the genesis of organic matter. Characterized by its unique balance of stability and …

Ethanol (CH3CH2OH) is a relatively common molecule, often found in star-forming regions.
Recent studies suggest that it could be a parent molecule of several so-called interstellar …

Context. The simultaneous detection of organic molecules of the form C 2 H n O, such as
ketene (CH 2 CO), acetaldehyde (CH 3 CHO), and ethanol (CH 3 CH 2 OH), toward early …

The formation of isomers of C 2 H 2 O—ketene (H 2 CCO), ethynol (HCCOH), and oxirene (c-
CHCHO)—was investigated in interstellar ice analogs composed of carbon monoxide and …

The family of isomeric H2C3O+• radical cations is of great interest for physical organic
chemistry and chemistry occurring in extraterrestrial media. In this work, we have …

Recent progress in observational astronomy and astrophysics has stimulated intensive
laboratory studies aimed at elucidating the mechanisms of evolution of molecular matter in …

Ethanol (C2H5OH) is one of the most common alcohol molecules observed in various space
media (molecular clouds, star formation regions, and, highly likely, interstellar ices), where it …

Nitriles are important constituents of extraterrestrial media. Nitriles are supposed to play a
crucial role in prebiotic chemistry occurring in the interstellar medium. In this work, we have …

This work was aimed at quantitative determination of the absorbed doses under X-ray
irradiation of cryogenic deposited films, particularly related to the matrix isolation …
