FAR INFRARED LASING FREQUENCIES OF CH2DOD

We obtained laser action from the CH2DOD molecule optically pumped by CO2 laser radiation. Eight lasing transitions were identified as originating from CH2DOD; an additional 21 transitions also lased, but were assigned to the CH2DOH molecule, and 2 to CH3OH, even though the isotopic purity of the sample was given as 98%. The relative intensity, relative polarization and frequency of all the lines were measured. The eight lines are distributed between 145.8 μm and 479.2 μm. © 1990 Plenum Publishing Corporation.
