Millimeter-wave Spectrum Analysis and Searches for 2-aminopropenenitrile (H2C=C(NH2)CN) toward the Galactic Center Sources Sgr B2(N1) and G+0.693-0.027
Original language description
We present an analysis of the millimeter-wave spectra of 2-aminopropenenitrile ( H2C=C(NH2)CN ), an alpha-aminonitrile of plausible prebiotic and astrophysical relevance. The molecule has a rotational spectrum that is in harmony with a large-amplitude motion of the amino group. Accurate rest transition frequencies are reported in selected regions between 158 and 324 GHz, along with extended and improved sets of molecular parameters for the ground state. In addition, several vibrational satellites were identified for the first time. Experimental results were used to search for 2-aminopropenenitrile toward two chemically rich interstellar sources in the Sgr B2 region of the Galactic center: the hot molecular core Sgr B2(N1S) and the molecular cloud G+0.693-0.027. We also searched for the reduced derivative, 2-aminopropionitrile ( CH3CH(NH2)CN ), in the former source. None of the molecules were detected, and the upper limits of their column densities were obtained.
