Chiral heavy transition metal complexes : towards a parity violation measurement at the molecular level

Orateur : Jeanne CRASSOUS (Institut des Sciences chimiques de Rennes, Université de Rennes1)

Parity violation (PV) at the molecular level is known to be responsible for a tiny energy difference between the two left-handed and right-handed enantiomers of a chiral molecule. This parity violation energy difference (PVED) has not yet been measured at the molecular level, although several attempts have been reported in the litterature. Highly accurate infra-red spectroscopy is considered as one of the most promising technique to evidence PVED [1]. In this context, several types of chiral heavy metal complexes have been considered as promising candidates for PVED measurements, such as for instance, chiral oxorhenium complexes that display subtle chirality features [2]. Here will be presented the joint collaboration between physicists, theoreticians, and synthetic chemists aiming at observing PV in chiral molecules.
