The infrared spectrum and the molecular structure of ozone and sulfur dioxide

Abstract

The writers have been interested in the fine experimental work on the infrared absorption spectrum of ozone by Gerhard,(1) but they cannot agree with his conclusions as to the structure of the ozone molecule, nor with the conclusions of Bailey, Cassie and Angus(2) in regard to that of sulfur dioxide. These authors have postulated for the molecules in question structures in the shape of an isosceles triangle with an apex angle less than 60°, but this seems very unlikely from several points of view.
