Infra-red Absorption of Carbon Bisulphide

Abstract

Two points of considerable interest in this spectrum have just come to light. With the view of instituting a comparison between the corresponding infra-red frequencies of gaseous and liquid carbon disulphide, the two spectra have been carefully re-examined in this laboratory. Using a prism spectrometer, we have found that the band of gaseous carbon disulphide at 11·4 μ, previously supposed1 to be a doublet with a maximal separation of 13 cm.-1, is really a triplet with maxima at 884, 878, and 870 cm.-1, having the appearance of a band with a medium intensity Q branch, Up to the present this band has been assigned to v3v1 but it is difficult to see how the triplet structure can arise from such a combination.
