Eleven new CW far infrared (FIR) laser lines have been observed in the 600 μm–1200 μm range from the CF2Cl2 (Fluorocarbon 12) molecule optically pumped by a CO2 laser. A 510−4–10−3 accuracy is achieved in the measurement of the FIR wavelengths.

The frequency offset between the CO2 pump center and the absorption line centers are measured using the transferred Lamb dip technique. Owing to a recent spectroscopic study of the CF235Cl2 molecule three lines may be assigned with great confidence as rotational transitions in thev6 vibrational band 923 cm−1 of this main isotope.
