The configuration and the conformation of two trifluoromethyl-triaryl-
ethane diastereomer pairs and of some sole isomers were determined usi
ng the through-space spin-spin coupling between fluorine atoms and the
hydrogen of the hydroxyl group. The molecule-mechanical calculations
support the results of the conformation-analysis based on the NMR data
