Infrared Absorption Bands in Hydrogen Sulphide

Abstract
Absorption spectrum of H2S in the region from 1.0μ to 10.0μ.—The absorption spectrum of hydrogen sulphide in the infrared has been investigated with a prism spectrometer from 1.0μ to 10.0μ. Two regions of absorption, one at 2.6μ and another 3.7μ were located, both of which revealed fine structure when examined under high dispersion.
