Pulse Radiolysis-Laser Flash Photolysis of Xanthene and Thioxanthene in Halocarbons

摘要

The excitation of 9-xanthenyl and 9-thioxanthenyl radicals generated in irradiated halocarbons results in chlorine atom transfer from the solvents. In the solutions containing oxygen, recovery of the photobleached 9-xanthenyl radical was observed. The detailed reaction mechanism was studied based on the kinetic analysis.
