Methanol and ten of its isotopomers have generated over 2000 far-infrared laser lines when pumped by CO₂ lasers. We report here 28 new laser lines from the isotopomers ¹²CD₃OH, ¹²CH₃OD, ¹²CH₂DOH along with their frequencies, relative intensities, relative polarizations and pump offsets. An efficient CO₂ laser with extended line coverage provided pumping from high J-fundamental, sequence and hot-band CO₂ transitions. Many new short-wavelength (below 100 µm) FIR laser transitions were observed.
