Abstract Twenty-seven new FIR, far-infrared, laser lines from the isotopomers of methanol: 12CD3OH, 12CH3OD, and 12CH2DOH, were obtained by optically pumping the molecules with an efficient cw CO2 laser. The CO2 laser provided pumping from regular, sequence, and hot-band CO2 laser transitions. The 2 m long far-infrared cavity was a metal-dielectric waveguide closed by two, flat end mirrors. Several short-wavelength (below 100 μm) lines were observed. The frequencies of 28 laser lines observed in this cavity (including new lines and already known lines) were measured with a fractional uncertainty limited by the fractional resetability of the far-infrared laser cavity, of 2 parts in 107.
