Two consecutive rotational transitions of the long cyanopolyyne HC11N, J = 39 → 38 and 38 → 37, have been detected in the cold dust cloud TMC-1 at the frequencies expected from recent laboratory measurements by Travers and coworkers, and at about the expected intensities. The astronomical lines have a mean radial velocity of 5.8(1) km s-1, in good agreement with the shorter cyanopolyynes HC7N and HC9N observed in this very sharp line source [5.82(5) and 5.84(5) km s-1, respectively].

Observations of Long CnH Molecules in the Dust Cloud TMC-1

We report detection of the J = 15.5-14.5 and 17.5-16.5 transitions of C8H, a sensitive upper limit for the J=10.5-9.5 transition of C7H, and measurements of two low-frequency transitions of C6H in

The Excitation Temperatures of HC9N and Other Long Cyanopolyynes in TMC-1

We report observations of seven different transitions of HC9N between 9.8 and 23.3 GHz in the cold, dark cloud TMC-1. Because of its lower rotational constant, HC9N is expected to yield a rotational

Laboratory Detection of the Linear Cyanopolyyne HC11N

The cyanopolyyne HC11N, the largest claimed interstellar molecule, has been detected in the laboratory. Its nearest microwave rotational transitions lie 0.13% lower in frequency than the lines

Laboratory Detection of the Carbon Chains HC15N and HC17N

The linear cyanopolyynes HC15N and HC17N were detected in the laboratory by Fourier transform microwave spectroscopy. Enough rotational lines of each species were measured in the 5-11 GHz frequency

Non-detection of HC11N towards TMC-1: constraining the chemistry of large carbon-chain molecules

Bell et al. reported the first detection of the cyanopolyyne HC_(11)N towards the cold dark cloud TMC-1; no subsequent detections have been reported towards any source. Additional observations of

The Slowly Expanding Envelope of CRL 618 Probed with HC3N Rotational Ladders

Lines from HC3N and isotopic substituted species in ground and vibrationally excited states produce crowded millimeter and submillimeter wave spectra in the C-rich protoplanetary nebula CRL 618. The

Far-infrared Detection of C3 in Sagittarius B2 and IRC +10216

Nine lines of the nu2 bending mode of triatomic carbon, C3, are detected in the direction of Sagittarius B2 and it is suggested that these molecules could be the dominant carriers of emission/absorption in the spectrum of bright far-infrared sources.


Recent detections of complex organic molecules in dark clouds have rekindled interest in the astrochemical modeling of these environments. Because of its relative closeness and rich molecular

A search for cyanopolyynes in L1157-B1

We present here a systematic search for cyanopolyynes in the shock region L1157-B1 and its associated protostar L1157-mm in the framework of the Large Program "Astrochemical Surveys At IRAM" (ASAI),

Deep K-band Observations of TMC-1 with the Green Bank Telescope: Detection of HC7O, Nondetection of HC11N, and a Search for New Organic Molecules

The 100 m Robert C. Byrd Green Bank Telescope K-band (KFPA) receiver was used to perform a high-sensitivity search for rotational emission lines from complex organic molecules in the cold



Detection of HC11N in IRC + 10°216

The observations of three rotational transitions (J = 70 → 69, 71 → 70, and 72 → 71) of HC11N (cyano-deca-penta-yne) in the microwave emission spectrum of the circumstellar envelope of the cool

A survey of carbon monoxide emission in dark clouds. [cosmic dust

Results are reported of a CO and $sup 13$CO survey of 68 dark clouds from the Lynds catalog. CO was detected in 63 of the 64 sources in which it was searched for, and the $sup 13$CO line was seen in

Long Chain Carbon Molecules in the Interstellar Medium

The long chain carbon molecules known as the cyanopolyynes (HCnN, n=3,5,7,9) are becoming increasingly more important in astrophysics. At present, the smallest member of the family, cyanoacetylene (
