Abstract
An assignment is proposed for the strong 127.0 μm far-infrared (FIR) line of13CD3OH known to be pumped with very high efficiency by the 10P(8) CO2 laser line. On the basis of spectroscopic clues derived from calculated molecular parameters and energies for13CD3OH, the 127 μm line is identified as the (nτK,J)=(116,17)→(125, 16) transition, and its companion 462.8 μm line as the (116,17)→(116,16) transition. Proposed partial assignments and predictions are also discussed for a number of other FIR laser lines in13CD3OH, CD3OH, CD3OD, CH3OD, CH3OH and13CH3OH.
