Aqueous solutions of thymine (T) in the presence of Fe(III) were irradiated under deaerated conditions at pH ≈2. The products of radiolysis were separated by two dimensional thin-layer chromatography. In the absence of any metal ion, the G(-T) is 2.6 but when Fe(III) is present during radiolysis, the G(-T) increases significantly and reaches a limiting value of 3.2. The yields of the hydroxylated products
胸腺嘧啶 (T) 在 Fe(III) 存在下的水溶液在 pH ≈2 的脱气条件下进行辐照。辐射分解产物通过二维薄层色谱分离。在没有任何金属离子的情况下,G(-T) 为 2.6,但当在辐射分解过程中存在 Fe(III) 时,G(-T) 显着增加并达到 3.2 的极限值。在 Fe(III) 存在下,胸腺嘧啶的羟基化产物的产率也会增加。结果由一种机制解释,该机制涉及 Fe(III) 与胸腺嘧啶的瞬态加合物的相互作用。
