Abstrakt: 1. The configuration of the OH group has been determined and the configurations of a number of other protons in the arnifolin molecule have been confirmed by means of the paramagnetically induced PMR spectra. 2. The paramagnetic shifts of a number of protons can be explained satisfactorily if it is assumed that the predominant association of the Eu(DPM)3is with the hydroxy group.
