title: Intracavity laser tomography of C(2) in an oxyacetylene flame.
abstract: C(2) may play an important role in soot formation in some flames and is a major species in acetylene combustion chemistry. In this Letter the technique of intracavity spectroscopy has been combined with a simple tomographic analysis to measure spatially resolved C(2)-concentration profiles in an oxyacetylene flame. We find that ground-state and excited-state C(2) are located in the same region of the flame, suggesting that conditions required for their formation are the same. Our results indicate that the C(2) concentration in the mantle region is close to its equilibrium value.
