采用60Coγ辐解，以异丙醇自由基为还原剂，研究了1，10－菲咯啉－5，6－醌（PQ）水溶液的单电子还原性质，获得了pH分别为9、≈7和≈4的水溶液幅照后的紫外、可见吸收光谱。pH9时吸收谱呈现出一个中心在490nm的宽吸收带，低于pH7，这个490nm附近的吸收要小得多，而且随溶液pH值的降低而下降。60Coγ辐解实验的观察与脉冲辐解结果一致。由此建议60Coγ辐解观察到的可见范围的吸收和脉冲辐解微秒范围所观察到的结果均由辐解终产物引起。质谱研究表明：pH3．3的水溶液经γ辐解生成一个质量数大于PQ的终产物。此终产物假定为由中性PQ半醌自由基歧化作用产生的PQH2．
The single-electron reduction of 1,10-phenanthroline-5,6-quinone (PQ) aqueous solution was studied by 60Coγ-irradiation and isopropanol as reducing agent. ≈ 4 aqueous solution after UV, visible absorption spectrum. The absorption spectrum at pH 9 shows a broad absorption band centered at 490 nm. Below pH 7, the absorption near 490 nm is much smaller and decreases with decreasing pH of the solution. The observation of 60Coγradiation experiment was consistent with the results of pulsed radiolysis. It is therefore suggested that the observed range of 60Co gamma-ray absorption and pulsed radiolysis microsecond range observed results are caused by the final radiolysis products. Mass spectrometry studies showed that: an aqueous solution of pH3.3 by γ-radiolysis to produce a mass greater than PQ of the final product. This final product is assumed to be PQH2 produced by neutral PQ semiquinone radical disproportionation.
