H-Atom Abstraction by Methyl Radicals in Organic Glasses

H-Atom Abstraction by Methyl Radicals in Organic Glasses 

Methyl radical decay in simple organic glasses made from acetonitrile [7, 17], methyl isocyanide [18] and methanol [19], at low temperatures, e.g., 77 K (liquid N2) commonly occur by H-atom abstraction from a molecule in the glass  

This unsatisfactory state of affairs changed in 1984 with a proposal [21] that these abnormal kinetics were a consequence of the inhomogeneity of the matrix. In the experiments that were carried out [21], the methyl radicals were produced in a methanol glass from methyl halides by photo-induced electron capture using traces of diphenylamine, reaction (28.17). It was suggested [21] that the radicals
