Photoactivation of methane has been kinetically studied in the CH4-NH3-H2O mixture, and the radical intermediates measured by the spin trap (PBN, α-phenyl-N-tert-butylnitrone)-EPR method.The trapped radicals were CH3O. (aN = 1.35, aβH = 0.20 mT), .CH2NH2 (aN = 1.46, aβH = 0.26 mT), and .CH=NH (aN = 1.48, aβH = 0.62 mT).It was suggested that .CH2NH2 was mainly provided by H abstraction from methylamine and the photolysis of CH3NH2 to CH3NH. and .CH2NH2 was low.The coupling of .CH2NH2 led to the formation of ethylenediamine, while CH3NH. decayed to CH2=NH from which the .CH=NH radical was generated by the H elimination.The water photolysis proceeded with a quantum yield of 0.06 in the gas mixture.
