Abstract:

Nitrous oxide, N2O, was photolyzed at 20 K in solid argon containing acetylene, C2H2, or a mixture of C2D2 and C2HD. The photolysis source was a xenon resonance lamp emitting mainly at 1470 A. This radiation produces ground state oxygen atoms. Infrared spectra showe that re-ACTION OCCURRED WITH C2H2 to produce absorption at 12143 cm and with the deuterated acetylenes to produce absorptions at 12142 and 12117 cm. The absorptions are assigned to ketene, thus showing that ground state oxygen atoms can react with acetylene to produce ketene. The activation energy for this reaction is below 8.1 kcalmole. Author
