辐射化学和放电化学的比较必然涉及强调热能和振动能所起的作用。除了注意假设在放电管中大多数电子碰撞的初始产物是中性激发态-即，“高温”状态--没有给出与之进行比较的放电类型的详细特征。凝聚态系统辐射化学的基本过程与气体放电化学的基本过程，特别是与慢电子的基本过程，是完全可以比较的。在甲烷的情况下，作为一个例子，在放电过程中乙炔的相对有效的生产归因于在二次过程中产生的振动激发的中间物质，如不能在气体的辐射化学中产生的。
Comparison of radiation chemistry and electric discharge chemistry necessarily involves emphasis on the roles played by thermal energy and vibrational energy. Except for noting the assumption that in a discharge tube most of the initial products of electron impact are neutral excited states—i.e., "high-temperature" states—no detailed characterization is presented of the type of electric discharge to which comparison is made. Elementary processes of the radiation chemistry of condensed systems are properly comparable with those of the discharge chemistry of gases, particularly with those processes involving slow electrons. In the case of methane, cited as an example, relatively efficient production of acetylene in discharge processes is attributed to production in secondary processes of vibrationally excited intermediate species such as cannot be produced in the radiation chemistry of gases.
