自由基分解反应R'→R+M的活化能可按如下经验公式快速估算:
Ed,R=Edo-V(R)
式中Edo是一个只和产物分子M的类型有关的常数,V(R)是原子团变更能。本方法的误差为±1~2 kcal/mol。

For the decomposition reaction of free radicals
R'→R+M
the activation energy has been estimated simply by the following equation:
E=Edo-V (R)
where Edo is a constant which depends only on the type of the product molecules M,V (R) is the redeformation energy of the group R.
