Fourier Transform information and optoacoustic absorbing transitions data of 13CD3OH of the new FIR laser emissions. An waveguide CO2 laser of 300 MHz tunability was used as optical source. Eight new FIR laser lines were observed and characterized. Three of these lines are associated to absorbing transitions appertaining to the 13CD3 assymmetric bending mode.
