Flame Spectrum of Barium: Red and Infra-Red Bands
THE diffuse bands appearing very strongly in the flame spectra of the alkaline-earth metals have been identified as due to the hydroxide radicals, CaOH, SrOH and BaOH. This identification is based on the work of James and Sugden 1 on hydrogen–air flames, employing photometric methods, and on work on...

on hydrogen–air flames, employing photometric methods, and on work on isotope shifts with deuterium, which have been obtained for CaOH by Gaydon

and for SrOH by Huldt and Lagerqvist

. The flame method has now been extended to the strong red and infra-red barium bands. |
