Abstract
We report on higly accurate absolute frequency measurement against a femtosecond frequency comb of 6 saturated absorption lines of formic acid (HCOOH) with an accuracy of 1 kHz. We also report the frequency measurement of 17 other lines with an accuracy of 2 kHz. Those lines are in quasi coincidence with the 9R(36) to 9R(42) CO laser emission lines and are probed either by a CO or a widely tunable quantum cascade laser phase locked to a master CO laser. The relative stability of two HCOOH stabilized lasers is characterized by a relative Allan deviation of 4.5 10 . They give suitable frequency references for H Doppler free two-photon spectroscopy.
