Short-Lived Radioactive Molecules
Precision measurements of molecular systems provide highly sensitive laboratories for exploring the possible violation of fundamental symmetries and search for new physics beyond the standard model physics [Barr14,Demi17,Safr18]. Radioactive molecules compound of heavy and deformed short-lived isotopes are predicted to offer unprecedented sensitivity to investigate parity and time reversal violation effects. However, the experimental knowledge of short-lived radioactive molecules is scarce, and quantum chemistry calculations has constituted the only source of spectroscopy information.
