自由基清除技术与电子自旋共振结合使用。光谱学已经被用于鉴定由苯偶姻、苯偶姻甲醚和苯偶酰的光解产生的自由基，参考它们作为自由基聚合的光活化剂的相对效率。被N-氧化物和亚硝基化合物捕获的自由基表明，虽然苯偶姻及其甲醚以类似的方式被光化学裂解，但后者更有效地产生自由基。提出了可能的机制。
The radical scavenging technique used in conjunction with e.s.r. spectroscopy has been employed to characterise radicals produced by photolysis of benzoin, benzoin methyl ether, and benzil with reference to their relative efficiencies as photoactivators for radical polymerization. Radicals trapped by N-oxides and nitroso-compounds indicate that while benzoin and its methyl ether are photochemically cleaved in a similar manner, the latter produces radicals more efficiently. Possible mechanisms are presented.
