Emission from CH and H radicals was monitored during the deposition of amorphous carbon films in a capacitively coupled rf glow discharge. Both the spectral and spatial distributions of the emission were studied. The relative intensity of the CH and H emission was found to be sensitive to changes in discharge parameters. Preliminary results indicate a correlation between the ratios of the CH to H emission intensities and the optical properties of the deposited films.
