Scientific paper

Details are reported here of the first laboratory detection of the low-J rotational transitions of HNCCC and DNCCC. The quadrupole coupling constants of N-14 and D nuclei in HNCCC and DNCCC are determined for the first time. The bond length of H-N is evaluated from rotational constants obtained for the models, and the results are compared with those of ab initio calculations of the linear and bent molecular structures of HNCCC by Botschwina et al. 1992.
