comments|The predictions are based on a combined fit involving
comments|v = 0 and v2 = 1 data.
comments|Pure rotational transition frequencies for both states were
comments|taken from
comments|(1) U. Fuchs, S. Brünken, G. W. Fuchs, S. Thorwirth,
comments|V. Ahrens, F. Lewen, S. Urban, T. Giesen, G. Winnewisser,
comments|2004, Z. Naturforsch., 59a, 861.
comments|Additional v = 0 frequencies were publised in
comments|(2) G. Cazzoli, C. Puzzarini, and J. Gauss,
comments|2005, Astrophys. J. Suppl. Ser. 159, 181.
comments|The v2 = 1 direct-l-type transitions
comments|were reported by
comments|(3) M. Winnewisser and J. Vogt,
comments|1978, Z. Naturforsch., 33a, 1323.
comments|Finally, ν2 infrared data come from
comments|(4) A. G. Maki, G. C. Mellau, S. Klee, M. Winnewisser, and W. Quapp,
comments|2000, J. Mol. Spectrosc. 202, 67.
comments|The dipole moment was assumed to agree with that of the main
comments|isotopic species, see e027501.cat.
comments|The 15N hyperfine splitting of about 20.6 kHz
comments|(2 : 1 intensity ratio) in the 1 0
comments|transition is likely too small to be of relevance in
comments|radio-astronomical observations. At higher J, this
comments|splitting decreases rapidly towards 13.7 kHz.
comments|The partition function takes into account both v = 0 and
comments|v2 = 1, but no hyperfine splitting.
comments|Individual non-zero contributions are given in parentheses.
