Scientists have long tried to experimentally demonstrate a certain symmetry property of the weak interaction—parity violation—in molecules. So far, this has not been possible. A new interdisciplinary effort led by a research group at the at the PRISMA+ Cluster of Excellence at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM) has now shown a realistic path to demonstrating this phenomenon. The approach includes aspects of nuclear, elementary particle, atomic and molecular physics as well as nuclear magnetic resonance (NMR). "Molecular parity nonconservation in nuclear spin couplings" is published in the current issue of the journal Physical Review Research.
