The12CH318OH molecule has been investigated for new far-infrared laser lines by optically pumping it with a cw waveguide CO2 laser. The larger tunability (318 MHz) with respect to a conventional CO2 laser permits the pumping of many12CH318OH lines. As a consequence 100 new laser lines have been discovered, ranging from 34.6 μm to 653.2 μm in wavelength. The infrared spectrum of12CH318OH has been observed and all the fundamental vibration energies measured.
