The measurements are from T. Amano and E.  Hirota, 1974, J. Mol. Spect.
{\bf 53}, 346. W. Steinbach and W. Gordy, 1975, Phys. Rev. {\bf A11}, 729, 
and R. L. Crownover, F. C. De Lucia and E. Herbst, 1990, Astrophys.J. {\bf 349,}
L29.  The calculation included the high resolution spectrum of the
$a^1\Delta-X^3\Sigma$ band, J. Brault, unpublished, and two microwave
transitions from the $a^1\Delta$ state from E. A. Cohen, M. Okunishi, 
and J. J. Oh, J. Mol. Struct. {\bf 352/353,} 283. Intensities of
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.
