The measurements and calculational method are from T. Amano and E.
Hirota, 1974, J. Mol. Spect.~{\bf 53}, 346. The Raman lines of
O$_2$ (M. Loete and H. Berger, 1977, J. Mol. Spect.~{\bf 68}, 317)
were used with the millimeter wavelength measurements and the submillimeter
line of W. Steinbach and W. Gordy (1973, Phys. Rev.~{\bf A8}, 1953) in a
combined fit of the v = 0 and v = 1 transitions. New measurements in the
far-infrared by L. R. Zink and M. Mizushima, 1987, J. Mol.~Spect.~
{\bf 125}, 154, are included. The intensities of the magnetic dipole
transitions have been calculated using the g values obtained
from magnetic resonance by K. D. Bowers, R. A. Kamper, and C. D. Lustig, 1959,
Proc.~Roy.~Soc.~London {\bf A251}, 565. The zero-frequency absorption
is included but the frequency is set to a synthetic frequency of $|g|J$ for the
given level. The intensity of these zero-frequency absorptions is based on
the synthetic frequency, using the equations for integrated intensity given
in Section 3.
