用正电子素o-Ps研究以亚甲兰为光敏剂在甲酸和水体系中激光诱导单态氧 ̄1O_2的形成。理论推导了o-Ps湮没率的改变与亚甲兰浓度之间的关系。经与实验结果对照证实了单态氧的产生
The singlet oxygen O induced by laser in a methanol- water system with photosensitizer
methylene blue (MB)
was probed by positronium. According to the theory of positron annihilation and chemical reaction kinetics
the relation between concentration of MB and variation of positron annihilation rate caused by
was deduced. The experimental results agree with the theory
confirming the formation of 1O2 in such a photochemical reaction.
