Abstract
A waveguide CO2 laser of wide tunability was used to pump infrared transitions of the 13CD3OD C-O stretching vibrational mode. The optoacoustic signal associated with the absorbing transitions served as a guide to search for new laser lines. We could observe 36 new far-infrared laser lines ranging from 57 to 1192 μm. All lines were characterized in wavelength, relative polarization, intensity, optimum pressure of operation, and precise offset measurements
