| ΔrH° | >39.7 | kcal/mol | KinS | Marcomini and Poë, 1984 | solvent: Decalin; Please also see Poë, 1981. The reaction enthalpy was derived from the enthalpy of activation, 39.6 ± 0.2 kcal/mol Poë, 1981, by assuming a negligible barrier for the radical recombination. This procedure was later considered to yield a low limit of the reaction enthalpy Poë, 1983 Marcomini and Poë, 1984 Marcomini and Poë, 1983 Coville, Stolzenberg, et al., 1983.
