Query: Probing weak force induced parity violation by high resolution
  mid-infrared molecular spectroscopy   To date no experiment has reached the level of sensitivity required to
observe weak nuclear force induced parity violation (PV) energy differences in
chiral molecules. In this paper, we present the approach, adopted at
Laboratoire de Physique des Lasers (LPL), to measure frequency differences in
the vibrational spectrum of enantiomers. We review different spectroscopic
methods developed at LPL leading to the highest resolutions, as well as 20
years of CO2 laser stabilization work enabling such precise measurements. After
a first attempt to observe PV vibrational frequency shifts using sub-Doppler
saturated absorption spectroscopy in a cell, we are currently aiming at an
experiment based on Doppler-free two-photon Ramsey interferometry on a
supersonic beam. We report on our latest progress towards observing PV with
chiral organo-metallic complexes containing a heavy rhenium atom.
