dc.description.abstractEnWe investigated the laboratory rotational spectra of H2 H2NC15N in the selected region between 192 and 507GHz employing a cyanamide sample in natural isotopic composition. Additionally, we recorded transitions of H2N13CN. We obtained new or improved spectroscopic parameters for the three isotopic species. Neither of the 15N isotopomers of cyanamide were detected unambiguously in the PILS data. Two relatively clean lines can be tentatively assigned to H215NCN. If confirmed, their column densities would imply a low 14N/15N ratio for cyanamide toward this source. The resulting line lists should be accurate enough for observations up to about 1THz. More sensitive observations, potentially at different frequencies, may eventually lead to the astronomical detection of these isotopic species. (3 data files).
