The current files were used to generate predictions of the NH rotational
spectrum for the CDMS catalog.

The observed transitions were taken from
(1) T. Klaus, S. Takano, and G. Winnewisser,
1997, Astron. Astrophys. 322, L1;
(2) J. Flores-Mijangos, J. M. Brown, F. Matsushima,
H. Odashima, K. Takagi, L. R. Zink, and K. M. Evenson,
2004, J. Mol. Spectrosc. 225, 189;

M. Simeckova, and S. Urban,
2004, J. Mol. Spectrosc., in press.


Note: Overlapping features
have been treated specially in (2) and (3). In (2), the
frequency of the overlapping hyperfine feature was corrected
so that the frequency could be attributed to the strongest
hyperfine component. In (3), the weights of the hyperfine
components were adjusted according to their contribution to
the measured frequency of the overlapping lines.

Also used in the fit were ground state combination differences
from an infrared emission spectrum by
(4) R. S. Ram, P. F. Bernath, and K. H. Hinkle,
1999, J. Chem. Phys. 110, 5557.
