The complete analysis and assignment of the 'H NMR spectra of 2-exo-bromonorbornane (1) and 2-bromoadamantane is reported, using high-field NMR and COSY and proton-carbon correlation experiments to assign the spectra. These data, together with those for the parent hydrocarbons, when combined with previous analyses of 1-bromoadamantane, 1-bromooctadeuterocyclohexane and the simple alkyl bromides, provide a data set of 38 proton SCS values for bromine in molecules of accurately known geometry. The effect of solvent on the SCS was investigated for 1 in five common solvents of very different polarity (C,D,, to DMSO). Only small ( < 0.1 ppm) solvent shifts were observed, apart from the 2-endo and 7s protons. A noteworthy feature of the SCS is the downfield shift of the CHX proton in all the series investigated, as X changes from C1 to Br to I. This is the reverse of the 'normal' trend and cannot be explained by present theories of SCS.
