Astrochemically Relevant Radicals and Radical–Molecule Complexes: A New Insight from Matrix Isolation

The reactive open-shell species play a very important role in the radiation-induced molecular evolution occurring cold areas of space and presumably leading to formation biologically relevant molecules. This review presents an insight into mechanism such processes coming from matrix isolation studies with main focus on experimental theoretical performed author’s laboratory during past decade. radicals radical cations produced astrochemically molecules were characterized by Fourier transform infrared (FTIR) electron paramagnetic resonance (EPR) spectroscopy. Small organic containing C, O, N atoms are considered view their possible complex (COMs) space, comparison earlier results is given. In addition, radical–molecule complexes generated isolated intermolecular matrices discussed connection model significance as building blocks for COMs formed under conditions extremely restricted mobility at cryogenic temperatures.
