Abstract
CONTINUING our previous work on the absorption of light by bismuth vapour, we have found that the vapour exhibits, at a temperature of about 1300°C., an absorption spectrum composed of a very great number of bands presenting a fine structure, and extending from 6500 to 4500. We have photo-graphed more than 400 bands in this region. These bands shade off towards the red end. At this high temperature, it is found that the vapour emits a fluorescent radiation orange-yellow in colour, and we have succeeded in photographing the fluorescence spectrum of the vapour at this temperature, containing about 24 bands ranging from 6600 to 5050. Hitherto bismuth has not been shown to possess either the fluorescence or channelled absorption spectrum in this region. Full details of the experiments, together with the photographs of the fluorescence and channelled absorption spectra of the vapour at this high temperature, will be published shortly.
