Abstract: The homogeneous photoexcited electron-transfer of PQ++-isopropyl alcohol systems in benzene solution was studied by means of spin trapping-ESR technique. Results show that PQ++ may be reduced, by the free radical (CH3)2ĊOH, to a free radical PQ·+; the rate of electron transfer can be accelerated greatly when benzophcnone is added to the photoreaction systems.

Key words: Paraquat salts, Spin trapping, Electron-transfer, Free radical
