For multiply measured transitions differing in
uncertainties by less than a factor of 2,
weighted averaged have been derived. Predictions should be viewed with caution above 4 THz.
Intensities were calculated based on $g$ values obtained by magnetic resonance in
(8) 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.
