Abstract
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.Keywords
