Abstract
The study of collisional transitional probabili ties for the de-excitation by inert gases of chemically activated sec-butyl radicals, excited to internal energies in excess of 40 kcal/mole, has been extended to H2, D2, N2, CO2, CH4, CD3F, CH3Cl and SF6. The diatomic gases display behavior similar to the rare gases, and on a preferred exponential model of collisional transition probabilities the average amount of energy transferred per collision is < E> expon approximately equal to 1.3 kcal/mole. Hydrogen atom rupture from chemically activated ethyl-d(1) radicals has been studied and is compared with a similar reaction of ethyl-d(3) radicals. The activation reactions were D atom addition to ethylene or to trans-ethylene-d(2). A very large normal statistical intermolecular secondary kinetic isotope effect of approximately greater than D atom substituent was found. (Author)
