β¦ Synopsis
In order to use chemical shift reagents (l-8) such as Eu(DPM)a and Pr(DPM)s (9) most effectively with polyfunctional molecules, it will be important to accuAwrlate infonaation regarding preferred sites of complexation.
This can be accomplished in either of two ways: (a)

## Abstract The determination of the enantiomeric composition of 2,2β²,6β²6β²βtetrasubstituted biphenyls using ^1^H NMR spectroscopy, in combination with chiral lanthanide shift reagents, has been studied. In general, the __S__ compounds give largeer induced shifts than the correspondind __R__ isomers
Pseudocontact effects between a paramagnetic metal ion and its ligands have proven helpful in the past in interpreting the nmr spectrum, in particular the proton n.m.r. spectrum, of the ligands.' Unusually large chemical shifts spread out a spectrum, simplify it, and often make it amenable to first
