J/A+A/449/855   Linelists for ammonia NH3, NH2D, ND2H, and ND3  (Coudert+, 2006)

Linelists for NH3, NH2D, ND2H, and ND3 with quadrupole coupling hyperfine components. Coudert L.H., Roueff E. <Astron. Astrophys. 449, 855 (2006)> =2006A&A...449..855C
ADC_Keywords: Atomic physics ; Radio lines Keywords: molecular data - catalogs - radio lines: ISM Description: Linelists with calculated line positions and line intensities for ammonia (NH3) molecule and its three deuterated variants NH2D, ND2H, and ND3 with quadrupole coupling hyperfine splittings. Lines in linelists are formatted as in the JPL data base (Pickett, Poynter, Cohen et al. 1998, J. Quant. Spectrosc. Radiat. Transfer, 60, 883). File Summary:

Global notes: Note (G1): Species code: 17000 for NH3 (table8), 20000 for ND3 (table11) 18000 for NH2D (table9), 19000 for ND2H (table10). A minus sign in front of the tag indicates that the value given for the frequency (Freq) is the observed one.
