Representative ratios of the rate constants for disproportionation ([k.sub.td]) and combination ([k.sub.tc]) in aliphatic hydrocarbons at 30[degrees]C are [k.sub.td]/[k.sub.tc] = 7.2 for t-butyl radicals, [k.sub.td]/[k.sub.tc] = 1.1 for cyclohexyl species, [k.sub.td]/[k.sub.tc] = 0.15 for primary propyl radicals, and [k.sub.td]/[k.sub.tc] [approximately equal to] 0 for allylic radicals (17).
