Determination of the Kinetics of Vinyl Radical Reactions by the Characteristic Visible Absorption Spectra of Vinylperoxyl Radicals

Abstract

Vinylperoxyl radicals surprisingly absorb in the visible region, whereas other peroxyl radicals absorb in the UV. Thus the kinetics of reactions of both vinylperoxyl radicals and vinyl radicals can be studied conveniently. The peroxyl radicals are formed by pulse radiolysis of oxygen-containing aqueous solutions of vinyl halides like 1 [Eq. (a)].
