Notes on the Infra-Red Spectrum and Molecular Structure of Ozone

The nature of the fine structure of the band at 14.2μ in the absorption spectrum of ozone has been determined with prism and grating spectrometers. These data, together with the fine structure of the 9.57μ band (previously resolved in the solar spectrum) render possible an unambiguous choice between the divergent views currently held with regard to the structure of the ozone molecule. It is concluded that the form of the isoceles triangle is acute, with the apex angle in the neighborhood of 34°.
