Abstract
When compounds of carbon and oxygen are excited to luminosity in vacuum tubes, they give rise to a large number of band systems, depending upon the conditions of electrical discharge. Most of these systems have been discussed by various authors, and on the basis of the theory of hand spectra have been attributed to transitions between different states of the molecule CO. Details of these systems, including those ascribed to the ionized molecule CO
+
, have been conveniently summarised by Jevons and by Kayser and Konen. Another band system (Deslandres' second negative) which occurs under favourable conditions has been attributed by Bair, and by Fox, Duffendack and Barker to the triatomic molecule CO
2
, since the bands appear most strongly in CO
2
, and are especially developed when a stream of this gas is passing through the discharge tube. The suggested CO
2
origin of these bands appears to be supported Smith's partial analysis of their structure.
