Abstract
The far-infrared absorption in solid alpha oxygen at 27 is shown to be definitively associated with the magnetic rather than orientational ordering in the crystal. A second magnetic excitation has been found at 6.5 . The properties of both absorptions are described using the excitation-wave formalism.
