✦ Synopsis

The frequencies of the ({ }^{Q} Q(12,1)) and the ({ }^{Q} Q(12,2)) transitions in the (\nu_{3}) band of ({ }^{12} \mathrm{CH}{3} \mathrm{~F}) and the frequency of the ({ }^{Q} R(4,3)) transition in the (v{3}) band of ({ }^{13} \mathrm{CH}{3} \mathrm{~F}) have been measured to an accuracy of (\pm 0.1 \mathrm{MHz}) relative to the (9 P(20)) and (9 P(32)^{12} \mathrm{CO}{2}) laser frequencies, respectively, by using them as the pump transitions in three-level double resonance experiments with both copropagating and counterpropagating beams. The frequencies of several transitions in the (2 v_{3}) (\nu_{3}) bands of these molecules were also measured to this accuracy by using them as the probe transitions in either three-level or four-level double resonance experiments.
