Hydrogen Bonding. 13. Infrared Study of the HF2- Anion in p-Toluidinium and Tetraalkylammonium Hydrogen Difluorides
The use of isotopic dilution has allowed analysis of the infrared spectrum of the HF2- ion in tetramethylammonium hydrogen difluoride.The F-H-F hydrogen bond in this salt is stronger than that in potassium hydrogen difluoride.This conflicts wit
