## Abstract The chemical shift differences of diastereotopic protons in aliphatic acyclic alcohols, mostly of the type Rο£ΏCH~2~ο£ΏCRβ²Rβ³ο£Ώ(CH~2~)~n~OH, have been investigated. Fairly small amounts of Eu(dpm)~3~ cause the spectra of these materials to simplify dramatically; indeed, even diastereotopic pr

β¦ Synopsis
In a recent cotmaunication by Pirkle and co-workers2, the use of chiral solvents and lanthanide shift reagents to distinguish nmso from d or 1 diastereonmric epoxides was described; a dramatic difference between the lanthanide induced shift of the mathlne protons In the meso cis-2,3--
