Temperature and site dependence of the rate of hydrogen and deuterium abstraction by methyl radicals in methanol glasses
Journal Article
·
· J. Phys. Chem.; (United States)
Rate constants are reported for hydrogen and deuterium abstraction by methyl radicals in CH/sub 3/OH and CD/sub 3/OD glasses in the ranges 5-89 and 77-97 K, respectively. At each temperature, they show a distribution due to a variation of radical trapping sites. The rate constants of this distribution are analyzed theoretically to yield a quantitative relation between tunneling rate and equilibrium tunneling distance. 20 references, 2 figures.
