Abstract
Mercury [Hg 6(3P1)]-photosensitized decomposition of ketene has been investigated at room temperature and at various pressures of ketene from the point of view of its utilization as a convenient source of triplet methylene. The relative quenching cross section of ketene has been determined and an analysis of the likely extent of direct absorption of light by ketene at 2537 Å in competition with the absorption by mercury atoms has been made. Some aspects of the reaction mechanism are discussed.Keywords
