Project B3

The physical properties and the tunneling dynamics of chiral molecules in the gas-phase will be studied by means of high-resolution infrared and terahertz spectroscopy. Purely light-driven methods to measure the chiral excess of mixtures and enantiomer-selective excitation schemes of ro-vibrational states will be developed. These techniques will open new prospects to chiral purification of racemic gas-mixtures. Furthermore, with the frequency comb-assisted precision spectrometers we aim for resolving the small energy differences between enantiomers to prove the predicted effect of molecular parity violation for the first time.The physical properties and the tunneling dynamics of chiral molecules in the gas-phase will be studied by means of high-resolution infrared and terahertz spectroscopy.
