Spectral Distribution of Different Regions of Illuminating Flare Flames.
Abstract
The flames of illuminating flame compositions which contained either the stoichiometric proportions of NaNO and Mg, or an excess of Mg, were examined at ambient pressures of 630, 150, 30 and 6 torr. The apparatus was arranged to obtain simultaneously a photograph of the flame and a spectrum from a region identifiable in the photograph. Changes in the intensity distribution were observed in the photographs when the ambient pressure was changed which appear to arise from the formation of concentrations of Mg. Sodium did not exhibit local concentration effects. Changes in the spectral intensity distribution at different distances above the candle are also observed. The changes associated with different radial positions are less noticeable. (Author Modified Abstract)
