An Absorption Band in Ethylene Gas in the Near Infrared

Abstract

The absorption spectra of gaseous ethane and ethylene have been investigated by photographic methods in the region λλ6500-9500. In the case of ethane no absorption was found. In ethylene a rather strong band was found at λ8720 which has a structure resembling that predicted by H. H. Nielsen for the oscillation-rotation bands of a molecule with moments of inertia in the ratio 1.4:1:0.14. The following very provisional values for the moments of inertia of the ethylene molecule are given: Ax=31×10^-40, Ay=27×10^-40, Az=3.8×10^-40.
