Significant amounts of carbon dioxide have been dissociated by a single flash of a xenon-filled quartz flash tube. For any one piece of quartz, the effectiveness of a discharge varied as expected with the various parameters. Considerable variation was found between any two pieces of quartz. The maximum output encountered was equivalent in the spectral region used to a blackbody of about 8000°K.
