|Title:||Single-pulse Carbon Dioxide Laser Photochemistry Of Ammonia And Oxygen|
|Abstract:||The photochemical reaction of 50 Torr of NH3 and 50 Torr of O2 was found to reach completion when the mixture was subjected to a single laser pulse. The laser employed was the P(32) line (00°1-10°0 transition) of a TEA CO2 laser with a pulse duration of 250 ns and a peak power of 1 GW/cm2. The experimental observations were as follows: (1) An intense yellow flash was generated immediately after the pulse; (2) The main reaction products analyzed were H2O, N2, N2O, N2H4, and H2. These results lead us to propose a chain reaction mechanism for the CO2 laser photooxidation of ammonia. © 1978 American Chemical Society.|
