The first measurements of the millimeter-and submillimeter (mm/submm)-wave rotational-torsional transitions in the v 3 ϭ 1 ground torsional state (n ϭ 0) of hydrogen peroxide are reported. The 149 newly measured transitions extend from 72 to 623 GHz in frequency and up to J ϭ 32 and K a ϭ 3 in rotat

✦ Synopsis
The pure rotational spectrum of the astrophysically very important linear molecule cyanoacetylene, HC 3 N, in the ground and vibrationally excited states has been studied in selected regions from 118 to 814 GHz using the Cologne terahertz spectrometer. Vibrational satellites appendant to the following vibrational states have been recorded and analyzed (v 4 , v 5 , v 6 ,
