Abstract
We have reinvestigated (CH3OH)-C-13 as a source of far-infrared (FIR) laser emission using a CO2 laser as a pumping source. Thirty new FIR laser lines in the range 36.5 mum to 202.6 mum were observed and characterized. Five o f them have wavelengths between 36.5 and 75 mum and have sufficient intensi ty to be used in LMR spectroscopy. Using Fourier-transform spectroscopic da ta in the infrared (IR) and FIR regions we have determined the assignment f or 10 FIR laser transitions and predict nine frequencies for laser lines wh ich have yet to be observed.
