Description

We have observed molecular-line transitions between 84 and 147 GHz in 24 dense southern molecular clouds with declinations south of -30 degrees using the Mopra and SEST radio telescopes. The results of observations of 2-mm and 3-mm transitions of the molecules CO, CS, C2H, CH3OH, HCN, HNC, HCO+, HC3N, OCS, HNCO and SO and several of their isotopomers are discussed in this paper, including ratios of the emission from the 12C, 13C and 18O isotopomers of CO, CS, HCO+, HCN and HNC. This paper lists the calibrated observational data for each molecular cloud and discusses some general properties of this sample. The calibration process for the Mopra antenna of the ATCA is described in an appendix.
