Abstract:

Various hydrocarbons have been reacted with active nitrogen in a supersonic flow system. The resulting chemiluminescence was invariably dominated by CN A doublet Pi and B doublet sigma to X doublet sigma emission. The intensity of this emission and the excited-state vibrational temperatures were strongly dependent upon the reactant hydrocarbon. Photon yields as high as 18.5 were measured for CN A doublet Pi to X doublet sigma emission when C2F4 was used as a reactant, which makes this system a very promising chemically pumped laser. Calculations have shown that, if the populations in the electronically excited states can be vibrationally cooled, it should be possible to achieve positive gain in the system.
