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 …

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 …

Radical SAM (RS) enzymes use S-adenosyl-l-methionine (SAM) and a [4Fe–4S] cluster to
initiate a broad spectrum of radical transformations throughout all kingdoms of life. We report …

Interstellar complex organic molecules (iCOMs) have been identified in different interstellar
environments including star forming regions as well as cold dense molecular clouds …

Conformers of carboxyl radical (HOCO) have been studied by IR spectroscopy in argon and
nitrogen matrices. In an argon matrix, only the lower-energy conformer trans-HOCO is …

Long electron spin coherence lifetimes are crucial for high sensitivity and resolution in many
pulse electron paramagnetic resonance (EPR) experiments aimed at measuring hyperfine …

EPR spectroscopy was extensively used for characterization of highly reactive paramagnetic
species produced by ionizing radiation in low-temperature solids for 60 years. The present …

This paper addresses the basic question of the impact of a chemically inert environment on
the radiation-induced transformations of isolated organic molecules in icy media at …

The CW-EPR lineshapes of methyl and small methyl-like radicals trapped in noble gas
matrices at liquid He temperatures are substantially different from the expected classical …

The combination of nuclear and electron magnetic resonance techniques, in pulse and
continuous wave regimes, is used to unravel the nature and features of the light-induced …
