STUDIES ON PHOTO-POLAROGRAPHY. VII. PHOTO-CURRENT OF DIMETHYLSULFOXIDE AND FORMATION OF METHYLSULFYNYLCARBONIUM ANION AT IRRADIATED DROPPING MERCURY ELECTRODE
The photo-current produced at a dropping mercury electrode irradiated by ultra-violet light in the dimethylsulfoxide (DMSO) solution was investigated. The formation of methylsulfynylcarbonium anion by the reaction of DMSO with the solvated electron was confirmed indirectly from the influence of ethanol as the H radical scavenger on the photo-current.
