✦ Synopsis

Several reports1 have appeared on the usefulness of tria(dipivalaaethanato)europim(IIl)

[Eu(DPM)d for simplifying the nmr spectra of alcohols by causingparamagnetic shifts, the magnitude of which depends on the distance of the protons tbrou&bomia or apace f'rmthe europium atom ccmplexed to the oxygen atom. In this paper is presented a new use for thia

Like Wahl and Peterson,' we have recently used the NMR shift reagent, tris(dipivalomethanato)europium III [Eu(dpm)JZp3 to simplify the spectra of 2-hydroxyadamantane and in addition we have also studied a variety of I-R-adamantanes(R = (CH2),CH, n= 1, 2, 3) and cyclopentanol. Wahl and Peterson have
