Xenon Tetrafluoride: Fluorine-19 High-Resolution Magnetic Resonance Spectrum.
The F(19) spectrum of XeF(4) dissolved in anhydrous hydrogen fluoride has been observed at two frequencies, yielding a F(19) chemical shift of 175 parts per million to lower field than the solvent and a Xe(129)-F(19) spin-spin coupling constant, confirmed by double irradiation, of 3860 cycles per second. Absence of fast F(19) chemical exchange and collapse of the Xe(131)-F(19) coupling by quadrupole relaxation may be inferred from the spectrum.
