TitlePaper, 'Note on the reversal of the spectrum of cyanogen' by G D [George Downing] Liveing and [James] Dewar
DescriptionLiveing and Dewar write: 'In the course of many observations on the reversal of lines of metallic spectra, we have frequently noticed dark shaded bands which appeared to be the reversals of bands ascribed to the oxides or chlorides of sundry metals; more particularly we have seen them when experimenting with compounds of the alkaline earths, and we have repeatedly obtained a reversal of the green magnesium-hydrogen series; but, until recently, we have never seen any reversal of the shaded bands of the spectrum of cyanogen, though our attention has been constantly directed to this spectrum.' They summarise the results of more recent investigations which 'show the reversal of the violet and ultra-violet bands of this spectrum'.
