Six FIR laser lines from CD3OH pumped by the 10R(36) and the 10R(18) CO2 laser lines are assigned to specific rotational energy levels in the excited C-O stretch state. It is found that their upper laser levels are shifted by a Fermi resonance between the C-O stretch vibration and the third and fourth harmonics of the torsional mode. The Fermi resonance shifts are +0.332/cm and +2.251/cm for the upper laser levels pumped by the 10R(36) and the 10R(18) CO2 laser lines, respectively. Calculated frequencies of the pump and the laser transitions agree with those of the pump CO2 laser lines and the observed FIR laser lines within estimated accuracy. 13 references.
