Modern applications of matrix isolation technique to investigation of radical species generated in atom–molecular chemical reactions

The potential of using the translational mobility of hydrogen, oxygen and fluorine atoms in the crystals and solid matrices of inert gases for initiating solid-phase cryochemical reactions and for investigating the stabilised intermediate particles generated in these reactions is discussed. The main spectroscopic methods used to study the stabilised particles are considered. Particular emphasis is placed on elucidation of the spectroscopic characteristics required for reliable identification and determination of the structure of new reactive intermediates. Methodological approaches to the solution of this problem are discussed. Examples of successful implementation of these approaches by various research groups are given.
