Abstract
The application of Cavity Ring Down Spectroscopy for the quantitative deter mination of CH densities in atmospheric flames has been investigated. Two d ifferent atmospheric flames have been studied: a premixed burner stabilised flat CH4/air flame and an oxyacetylene flame from a welding torch, which i s used for diamond deposition. For the methane flame density profiles of CH are obtained and compared with densities calculated by De Goey and Van Oij en (1998). The temperature is derived from the measured Boltzmann distribut ion. The data from the oxyacetylene flame are compared to LIF profiles meas ured by Klein-Douwel et al. (1995).
