Abstract :
A three-laser heterodyne system was used to frequency measure 11 previously observed optically pumped far-infrared (FIR) laser emissions of CHD2OH. These newly measured frequencies have fractional uncertainties of ±2×10-7 and correspond to laser wavelengths ranging from 47.8 to 238.0 μm. The pump laser offset frequency was measured for 15 CHD2OH FIR laser emissions.
