Xenon Tetrafluoride: Fluorine-19 High-Resolution Magnetic Resonance Spectrum

The F19 spectrum of XeF4 dissolved in anhydrous hydrogen fluoride has been observed at two frequencies, yielding a F19 chemical shift of 175 parts per million to lower field than the solvent and a Xe129-F19 spin-spin coupling constant, confirmed by double irradiation, of 3860 cycles per second. Absence of fast F19 chemical exchange and collapse of the Xe131-F19 coupling by quadrupole relaxation may be inferred from the spectrum.
