LARGE STATISTICAL SECONDARY ISOTOPE EFFECTS IN NON-EQUILIBRIUM REACTIONS SYSTEMS. UNIMOLECULAR DECOMPOSITION OF CHEMICALLY ACTIVATED ETHYL-D1 AND ETHYL- D3 RADICALS
Abstract
Hydrogen atom rupture from chemically activated ethyl-d1 radicals was studied and is compared with a similar reaction of ethyl-d3 radicals. The activation reactions were D atom addition to ethylene or to trans-ethylene-d2. A very large normal statistical intermolecular secondary kinetic isotope effect of > 1.5 per D atom substituent was found. The experimental results are in concordance with the theory and conform to the formulation of these effects previously given. The calculated effect is 1.6. These magnitudes per D atom are considerably enhanced over those obtained for butyl radicals.
