Abstract

Hydrogen, methane, nitrogen, ethane, ammonia, ethylenimine, dimethylamine, azomethane, and a polymer were identified as products in the photochemical decomposition of methylamine. Quantum yields of most of these products were determined under a variety of experimental conditions at room temperature. By use of CH/sub 3/ND/sub 2/ and of CD/sub 3/NH/sub 2/ as well as by use of scavengers, it was shown that the main primary process is the elimination of a hydrogen atom. This is followed by abstraction from the substrate to form hydrogen gas. Other steps in the mechanism are suggested and evidence for some of them presented. (auth)
