"In the study of free radicals and other unstable substances, an inherent difficulty is the maintenance of a suitable concentration... The intent of the [matrix isolation] method is to trap active molecules in a solid matrix of inert material, crystalline or glassy... The active material can be produced in a variety of ways: by chemical reaction involving two reactants, by pyrolysis, by dissociation in a glow discharge or an arc, or by photolysis."
