Abstract : The rates of decomposition of the secondary alkyl radicals 2-butyl, 2-pentyl, 2-hexyl, 2-heptyl and 2-octyl were measured by an internal comparison method at 300 K. Activation to a level around 45 kcal/mole was by addition of H atom to the appropriate alpha-olefin. Calculated rate constants agree well with the experimental values. The data illustrate the effect on rates of quantum statistical-weight changes due to structural increments in the series. (Author)
