摘要：

The HNCCC molecule, an isomer of cyanoacetylene HCCCN, has been identified in TMC-1 through the observations with the Nobeyama 45 m telescope, considering the observed spectral pattern, results of ab initio calculations, and laboratory microwave spectroscopy. The column density of HNCCC in TMC-1 has been determined to be 3.8(0.6) x 10(11) cm-2, which is 160-450 times smaller than that of HCCCN.
