J/A+AS/133/29 Molecular line survey towards UC HII (Hatchell+ 1998) ================================================================================ A survey of molecular line emission towards ultracompact HII regions Hatchell J., Thompson M.A., Millar T.J., Macdonald G.H. =1998A&AS..133...29H (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: H II regions ; Radio lines Keywords: ISM: molecules - ISM: clouds - ISM: HII regions - radio line: ISM - stars: formation - molecular processes Description: The tables give identifications for molecular lines detected in the survey of ultracompact HII regions. The survey covers 14 sources: G5.89, G9.62, G10.30, G10.47, G12.21, G13.87, G29.96, G31.41, G34.26, G43.89, G45.12, G45.45, G45.47, and G75.78. For each source, we observed up to ten 1~GHz bands between 200 and 350~GHz, covering lines of more than 30 species including multiple transitions of CO isotopes, CH_3_OH, CH_3_CCH, CH_3_CN and HCOOCH_3, and sulphuretted molecules. The tables give the measured line parameters of observed frequency {nu}(obs), peak temperature T_R_^*^ and linewidth {Delta}{nu}_1/2_ for each line. Each independent detection of a particular line is given. The species, transition, rest frequency and upper level energy (E_u_/k) are given for identified lines.
