摘要-研究了叶绿素在体内和胶束水溶液中的光氧化作用。通过自旋捕获实验，发现如果存在氧，则在这些系统中光产生羟基自由基。光学研究表明，叶绿素的光破坏速率是自旋陷阱依赖的。这表明，羟基自由基可能在叶绿素的破坏中起着关键作用。
Abstract— The photooxidation of chlorophylls in vivo and in aqueous micellar solutions has been investigated. Through spin trapping experiments, it was found that hydroxyl radicals are photo‐produced in these systems if oxygen is present. Optical studies indicate that the rate of photo‐destruction of chlorophyll is spin trap dependent. This suggests that the hydroxyl radical may play a key role in the destruction of chlorophyll.
