Abstract:New cascade laser transitions of12CH2F2 at 172.50mgrm, 208.83mgrm, 220.44mgrm, 223.99mgrm and 250.61mgrm are reported. A waveguide FIR laser was pumped with a quasi cw12C16O2 laser operating on the 9R32 line. Together with the already known lines at 184.3mgrm, 196.1mgrm and 235.9mgrm, the laser lines can be assigned to rotational transitions in the ngr9 vibrational band of12CH2F2 and to refill transitions of the vibrational ground state ngr0.
