The entry has been generated from a combined fit.
The ν2 band origin was determined
from IR transitions published by
(1) T. J. Sears,
1985, J. Opt. Soc Am. B 2, 786;
Q(10) was omitted from the fit.
The v = 0 data were taken from
(2) P. Verhoeve, E. Zwart, M. Versluis, M. Drabbles, J. J. ter
Meulen, W. L. Meerts, A. Dymanus, and D. B. McLay,
1990, Rev. Sci. Instrum. 61, 1612;
from
(3) T. Amano, T. Hirao, and J. Takano,
2005, J. Mol. Spectrosc. 234, 170;
and from
(4) L. Pagani, F. Daniel, and M.-L. Dubernet,
2009, Astron. Astrophys. 494, 719;
see also e029506.cat.
The v2 = 1 data were taken
from
(5) T. Amano, T. Hirao, and J. Takano,
2005, J. Mol. Spectrosc. 234, 170;
see also e029509.cat.
The predictions should be reliable up to
J = 15, mayb even 20.
Note: The partition
function takes into account the 14N hyperfine
splitting as well as contributions from the vibrationally excited
v2 = 1 state ! Individual
non-zero contributions are given in parentheses.
The transition dipole moment was derived from an
ab initio calculation by
(6) H. S. P. Müller,
2010, unpublished.
