Thaddeus has reported six new carbon chains detected in the laboratory, all of astrophysical interest: C7H,126 C8H,127 C9H,128 C11H,129 HC11N,130 and HC13N.131 The microwave and millimeter wave frequencies of these molecules are now known to a fraction of 1 km s-1 in radial velocity. HC11N, which for 14 years has stood as the largest interstellar molecule, was unfortunately misidentified. The claimed lines in IRC+10216 and TMC-1 are some entirely different molecule - the actual lines of HC11N lie 0.13% lower in frequency, and are so far undetected. However, C8H has been identified in IRC+10216 on the basis of the laboratory data,127 and it seems likely that some or all of the other chains on this list will be detected in the fairly near future. The CfA/Harvard group has also been involved in investigating other species, including N2H+,132 C4H,133 C3N,134 and HC3S.135 The submillimeter spectra of Orion/KL6 and other so-called ``hot core'' objects require detailed spectroscopy of complex organic molecules up to high frequencies. De Lucia, Herbst and co-workers have studied the submillimeter spectra of CH3OD,136 CH3CHCH2,137 C2H5CN,138 trans- and gauche ethyl-alcohol,139,140 and DCOOCH3.141 Spectra up to the terahertz region have been measured in the Cologne laboratory of SO,142 CN,143 and CH3OH,144 and in Lille of NH3.146 The microwave spectra of the simplest amino acid, glycine, have recently been measured by Lovas' 145 for both conformers, enabling new astronomical searches. The Lille group has also measured millimeter spectra of HCOCN,147 H2SiO,148 Si2H2,149 C2H3+,150 and NH2.151
