Abstract
A method for studying the nature of electronic excited state under photooxidation is proposed. It is shown by an example of the oxidation of chlorophyll a with p-benzoquinone that the formation of cation-radicals of pigments proceeds only through the triplet state. On the basis of experimental data the values of the rate constants of formation of chlorophyll cation-radicals through the singlet-excited state (K2(1)--10(7) M-1 s-1) and triplet state (Kr=10(9) M-1 s-1) of the pigment are evaluated.
摘要
提出了一种研究光氧化作用下电子激发态性质的方法。以对苯醌氧化叶绿素a为例表明，色素阳离子自由基的形成仅通过三重态进行。根据实验数据，估算了色素通过单重激发态（K2(1)--10(7) M-1 s-1）和三重态（Kr=10(9) M-1 s-1）形成叶绿素阳离子自由基的速率常数。
