Abstract
Methanol and ten of its isotopomers have generated over 2000 far-infrared laser lines when pumped by $CO_{2}$ lasers. We report here 28 new laser lines from the isotopomers $^{12}CD_{3}OH$, $^{12}CH_{3}OD$, $^{12}CH_{2}DOH$ along with their frequencies, relative intensities, relative polarizations and pump offsets. An efficient $CO_{2}$ laser with extended line coverage provided pumping from high J-fundamental, sequence and hot-band $CO_{2}$ transitions. Many new short-wavelength (below 100 $\mu$m) FIR laser transitions were observed.
