摘要：

The fluorescence of tryptophan and some related derivatives was found to be quenched by hydrogen peroxide. The quenching mechanism was shown to be essentially dynamic in nature, Without any ground-state complex formation, and it is interpreted as resulting through an electron transfer from the excited indole ring to hydrogen peroxide. © 1979.
