EPR of UV Photolyzed Tetramethylammonium Acetate and Tributyltin Acetate Powders

Abstract

The electron paramagnetic resonance investigation of tetramethylammonium acetate ((CH<inf>3</inf>)<inf>4</inf>NCH<inf>3</inf>COO) and of tributyltin acetate ((C<inf>4</inf>H<inf>9</inf>)<inf>3</inf>SnCH<inf>3</inf>COO) powders under UV photolysis were carried out at 120K. Some damage centers were formed by the UV photolysis which are attributed to ĊH<inf>3</inf> and CO<inf>2</inf>- radicals in the first substance and to CH<inf>3</inf>ĊŌO radical in the second. The g values of the radicals were found to be 2.0642, 2.0305 and 2.0058 respectively. No signals were detected at different doses of the gamma irradiation and UV photolysis for both samples at the room temperature.
