Abstract
A1H and 19F magnetic resonance study of the difluoride ion in a single crystal of KHF2 at room temperature has been performed with the object of confirming the predicted angular dependence of the dipolar-split 1H and 19F spectra. An analysis of the line-splittings shows that in this salt the proton is centred to within ± 0.025 Å, that the mean H—F bond length, 〈r–3〉1/3, is 1.168 ± 0.0025Å, which with the appropriate motional correction yields a value for the rz parameter of 1.138 ± 0.004 Å.Keywords
