记录了含氟阴离子在CH3CN溶液中的氟核磁共振位移。观测到的-74ppm的位移与最近报道的-150.6 ppm的值有很大不同。先前观察到的信号归因于Hf2-阴离子。它还表明，先前报道的和未解释的卫星It约-131ppm是由于SiF62-离子造成的。F-在异丙醇、乙醇和CH2Cl2中的化学位移也被记录下来，表明F-位移强烈地依赖于溶剂。
The fluorine NMR shift of the fluoride anion in CH3CN solution has been recorded. The observed shift of -74 ppm significantly differs from the value of -150.6 ppm recently reported. The previously observed signal is attributed to the HF2-anion. It is also shown that the previously reported and unexplained satellite it about -131 ppm is due to the SiF62-anion. The chemical shifts of F-in isopropanol, ethanol and CH2Cl2have also been recorded and suggest that the F-shifts are strongly solvent dependent.
