Cover Picture: Ab Initio Calculation of Parity-Violating Chemical Shifts in NMR Spectra of Chiral Molecules (ChemPhysChem 4/2003)

4_04/2003The cover picture shows an intriguing effect in molecular systems, which is caused by the parity-violating weak interactions: The chemical shifts of magnetic nuclei are predicted to differ for the two enantiomers of a chiral compound! While in the R enantiomer the nucleus (red) of the yellow center gives rise to the red NMR signal, the corresponding nucleus of the S enantiomer (green) is expected to absorb at a slightly different frequency. The ab initio approach presented by Laubender and Berger on pp. 395–399 allows for a prediction of the resulting parity-violating line splitting (shown in the black curve) and for the identification of molecular candidates that are well-suited to the first successful measurement of parity-violating effects in molecules.
