Chirality is a fundamental concept in physics, chemistry and biology. In physics objects of opposite chirality are connected by the parity operation (P), which combines with charge conjugation (C) and time reversal (T) in the CPT theorem: a mirror universe, where all particle positions are reflected about some plane (parity inversion), where all particles are replaced by their anti-particles (charge conjugation) and where all their momenta reversed (time reversal), will evolve according to the same physical laws as the present universe. Although the theorem states that the combined CPT symmetry is conserved by all physical processes and by the four fundamental forces (gravitation, | Chirality is a fundamental concept in physics, chemistry and biology.

The present project addresses a more fundamental aspect of chirality, namely it aims at providing the first experimental observation of the energy difference between enantiomers of chiral molecules due to parity violation (PV). A successful experiment will have a significant impact on our understanding of the stability and dynamics of chiral molecules as well as the origin of biochirality. Such a project is inherently multidisciplinary and is expected to lead to important advances in spectroscopy, | The present project addresses a more fundamental aspect of chirality, namely it aims at providing the first experimental observation of the energy difference between enantiomers of chiral molecules due to parity violation (PV).
