Electroweak quantum chemistry leads to the prediction of a new isotope effect for molecules that are chiral as a result of isotopic substitution (see picture). The electron–nucleon interaction mediated by the Z‐boson results in surprisingly large parity‐violating energy differences Δ pv E between isotopic enantiomers. For isotopic substitution of heavier atoms such as 35 Cl/ 37 Cl Δ pv E is almost as large as in ordinary chiral molecules. This is important for spectroscopic experiments on parity violation.
