Here, we report the first gas phase study of a linear triatomic specieSNP. This compound was prepared by a low-pressure pyrolysis 2,3 of SP(N 3 ) 3 at about1000°C.SP(N 3 ) 3 → SNP + 4 N 2The continuous flow was used during the whole measurement with the total pressurekept at about 15 µbar. The predictions of transition line frequencies were carried outwith the help of CCSD(T) calculations. The basis set of the molecular parameters wasdetermined by the SPFIT program. The measurements of the rotational spectra, the lineassignments as well as the molecular parameters derivation of the SNP molecule wereperformed for the first time.References[1] L. M. Ziurys, S. N.
