title: Parity non conservation: NMR parameters in chiral molecules.
abstract: The formula giving the parity-violating electroweak interaction contribution to the magnetic shielding tensor has been applied to enantiomers containing thallium. Using an extended Hückel relativistically parameterized method a chemical shift difference close to 1 mHz at 11.7 T is calculated in two couples of enantiomers. Such a difference is slightly lower than the extreme line width which may be actually reached in ultra-high resolution NMR.
