Abstract : In order to investigate the properties of air mixtures and related gases cascade arc chambers of 5 mm diam. are fed with the gas desired. Careful measurements of the field strength E and the total radiation U depending on current and gas composition were carried out. An apparatus for spectroscopic temperature measurements with evaluation by computer technique on-line was installed. Temperature measurements were performed. For the special case of hydrogen, viscosity measurements done. In the spectrum of an oxygen arc burning in a quartz tube at low currents the affinity continuum due to attachment of free electrons to neutral oxygen atoms could be found and measured whereby the affinity energy could be determined.
