摘要：

The existence of methyl radicals in the photo-Kolbe reaction was confirmed by means of in situ measurements with flow electron spin resonance for deuterated acetic acid. From the dependence of the flow rate, two reaction paths were deduced for methyl radical formation. These were assigned to those caused by trapped holes and . OH radicals. It is suggested that the former path is dominant when platinum has not been loaded onto TiO2 powder.
