Parity-violating contributions to nuclear spin-rotation interactions and to NMR shielding constants in tetrahedral molecules

In natural processes involving weak interactions, a violation of spatial parity conservation should appear. Although the parity-violation effects are expected to be observable in molecular systems, their tiny magnitude has prevented detection date. We present theoretical analysis four-component relativistic nuclear-spin-dependent parity-violating nuclear spin-rotation and NMR shielding tensors set tetrahedral chiral molecules. This work emphasizes significant contribution ligands electronic structure center enhancing these effects, paving way for targeted design promising molecules measurements.
