摘要
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 CH2Cl2 have also been recorded and suggest that the F- shifts are strongly solvent dependent. © 1990.
