摘要: Abstract In an ordinary acetylene-air-flame the vapours of potassium and rubidium at low concentrations are ionized to a considerable degree. At higher resonance lines these elements strongly self-absorbed. Moreover atoms associate molecules. It is very difficult measure in hot flame without too much ionization, association or selfabsorption.
