New CH2F2 FIR Laser Lines Pumped by a Tunable WG CO2 Laser

8 new large offset FIR laser lines of CH2F2 have been discovered by pumping with a high tunability waveguide CW CO2 laser. Optoacoustic mesurements of CH2F2 have also been performed and the pump offsets of the new and of previously known lines have been measured and checked. Some assignments are proposed and a few assignments found in literature are checked.
