Oxidation reactions by radicals constitute a very important class of chemical reactions in solution. Radiation Chemistry methods allow producing, in a controlled way, very reactive oxidizing radicals, such as OH, CO₃, NO₃, SO₄, and N₃. Although the radical cation of water, H₂O, with a very short lifetime (shorter than 1 ps) is the precursor of these radicals in aqueous solutions, its chemistry is usually known to be limited to the reaction of proton transfer by forming OH radical. Herein, we stress situations where H₂O undergoes electron transfer reaction in competition with proton transfer.
自由基的氧化反应是溶液中非常重要的一类化学反应。辐射化学方法可以以可控的方式产生非常活泼的氧化自由基，如 OH、CO₃、NO₃、SO₄ 和 N₃。尽管水的自由基阳离子 H₂O 的寿命非常短（短于 1 ps），是水溶液中这些自由基的前体，但通常认为其化学性质仅限于通过形成 OH 自由基进行质子转移反应。在这里，我们强调了 H₂O 经历电子转移反应与质子转移反应竞争的情况。
