Vibrationally excited vinyl cyanide in Sgr B 2 ( N )
نویسندگان
چکیده
We analyse the excitation of 114 rotational transitions of vinyl cyanide (acrylonitrile), C 2 H 3 CN, in its ν 11 and ν 15 vibrational states, together with 98 transitions in the ground state. The data were taken from the SEST line survey of Sgr B2(N) in the 1.3 mm band. For the lines with energies above 200 K a rotational temperature of 440

Detection of vibrationally excited methyl formate in W51 e2
Context. Hot cores in molecular clouds, such as Orion KL, Sgr B2, W51 e1/e2, are characterized by the presence of molecules at temperature high enough to significantly populate their low-frequency vibrationally excited states. For complex organic molecules, characterized by a dense spectrum both in the ground state and in the excited states, such as methyl formate, ethyl cyanide or dimethyl eth...
متن کاملRotational spectroscopy of isotopic vinyl cyanide , H 2 C = CH − C ≡ N , in the laboratory and in space ⋆
The rotational spectra of singly substituted 13C and 15N isotopic species of vinyl cyanide have been studied in natural abundances between 64 and 351 GHz. In combination with previous results, greatly improved spectroscopic parameters have been obtained which in turn helped to identify transitions of the 13C species for the first time in space through a molecular line survey of the extremely li...
متن کاملInterstellar Isomers: The Importance of Bonding Energy Differences
We present strong detections of methyl cyanide (CH3CN), vinyl cyanide (CH2CHCN), ethyl cyanide (CH3CH2CN) and cyanodiacetylene (HC4CN) molecules with the Green Bank Telescope (GBT) toward the Sgr B2(N) molecular cloud. Attempts to detect the corresponding isocyanide isomers were only successful in the case of methyl isocyanide (CH3NC) for its JK = 10 − 00 transition, which is the first interste...
متن کاملVibrationally excited HC 3 N toward hot cores
We report IRAM 30-m observations of vibrationally excited rotational transitions of HC 3 N toward a sample of six ultra–compact Hii regions. In addition, Effelsberg 100-m and Plateau de Bure Interferometer measurements were conducted toward the region G10.47+0.03. We detected the v 7 = 1 state of cyanoacetylene toward all six regions and the v 6 = 1 line toward five of them. Toward G10.47+0.03,...

We present the results of our survey toward the proto–planetary nebula CRL 618 for several large, highly saturated, oxygen-bearing organic molecules of biological importance including acetaldehyde (CH3CHO), acetic acid (CH3COOH), dimethyl ether (CH3OCH3), ethanol (CH3CH2OH), formic acid (HCOOH) and methyl formate (HCOOCH3); large carbon chain molecules including methyl cyanide (CH3CN), methylcy...
