Investigation of the purity of antimony pentafluoride using F-19 NMR
Résumé
Samples of antimony pentafluoride from different syntheses as well as commercial products were investigated by 19F and 1H NMR and compared. HF was identified as impurity and SbF6 specie is also present. Their amounts have been correlated through a method based on 19F NMR.
