Laser Studies of Gas Phase Radical Reactions.

Abstract

Pulsed discharges have been used to prepare carbon fluoride (CF2) and CF radicals in the presence of oxygen (O) atoms, and the decay rates of both species have been measured simultaneously following the pulse. This has resulted in relative rates of the CF2 and CF radical removal being obtained, and as the rate constant for the O + CF2 reaction is known, this has enabled an estimate for the rate constant k or O + CF to be made. In this study Figures 1 and 2 show the first time resolved interferograms and their Fourier transforms obtained with the infrared emission spectrometer. The emission source was a pulsed black body: the time resolved spectra were taken in the near ir region with a photodiode and thus show a long wavelength cutoff which is not representative of the true emission.
