摘要: C2 may play an important role in soot formation some flames and is a major species acetylene combustion chemistry. In this Letter the technique of intracavity spectroscopy has been combined with simple tomographic analysis to measure spatially resolved C2-concentration profiles oxyacetylene flame. We find that ground-state excited-state are located same region flame, suggesting conditions required for their same. Our results indicate concentration mantle close its equilibrium value.
