Abstract

We report on absolute measurements of saturated-absorption line-center frequencies of room-temperature trifluoromethane using a quantum cascade laser at 8.6 μm and the frequency modulation spectroscopy method. Absolute calibration of the laser frequency is obtained by direct comparison with a mid-infrared optical frequency comb synthesizer referenced to a radio-frequency Rb standard. Several sub-Doppler transitions falling in the $υ_{5}$ vibrational band are investigated at around $1158.9 {cm}^{- 1}$ with a fractional frequency precision of $8.6 \cdot 10^{- 12}$ at 1-s integration time, limited by the Rb-clock stability. The demonstrated frequency uncertainty of $6.6 \cdot 10^{- 11}$ is mainly limited by the reproducibility of the frequency measurements.
