Abstract

The pure rotational spectra of the amidogen radical 15ND2 and of the imidogen radicals 15ND and 15NH were recorded by a millimetre- and a submillimetre-wave spectrometer up to the THz region. This work represents the first experimental laboratory detection of both 15ND2 and 15ND. In the case of the amidogen radical, the analysis of the data provided a large set of rotational, electron spin-rotation and hyperfine terms. In the case of 15ND, our transitions were merged with the already existing data for NH, ND and 15NH and analysed in a multi-isotopologue Dunham-type fit. As far as 15NH is concerned, the N = 1-0 transition, for which just one fine-structure component was known (Bailleux S, Martin-Drumel MA, Margulés L, Pirali O, Wlodarczak G, Roy P, Roueff E, Gerin M, Faure A, Hily-Blant P. High-resolution Terahertz spectroscopy of the 15NH 3S-. Astron Astrophys 2012; 538: A135(1--5)), was detected around 1 THz..
