Discovery and frequency measurement of short-wavelength far-infrared laser emissions from optically pumped 13CD3OH and CHD 2OH


A three-laser heterodyne system was used to measure the frequencies of twelve previously observed far-infrared laser emissions from the partially deuterated methanol isotopologues 13CD3OH and CHD 2OH. Two laser emissions, a 53.773 μm line from 13CD3OH and a 74.939 μm line from CHD2OH, have also been discovered and frequency measured. The CO2 pump laser offset frequency was measured with respect to its center frequency for twenty-four FIR laser emissions from CH3OH, 13CD 3OH and CHD2OH. © 2007 Springer-Verlag.
