Investigations in the infra-red region of the spectrum. Part III.—The absorption spectrum of carbon disulphide

Abstract

The absorption spectrum of liquid carbon disulphide has been previously determined by Coblentz. The apparatus described in Part I of the present series offers a higher degree of resolution and a greater range of the spectrum than were available to the former worker. It was accordingly decided to examine this substance in the vapour state, and this paper gives an account of the absorption spectrum between 1 and 22 μ .
