Sulfur and Silicon Isotope Effects in Fluorine Nuclear Magnetic Resonance Spectroscopy

摘要

Satellites due to fluorine on S33have been observed in the F19NMR spectrum of sulfur hexafluoride. Values of the S33sngbnd;F coupling constant and of the S33isotope effect on the fluorine chemical shift have been obtained from the spectrum. We have also observed a S34isotope effect on the fluorine chemical shift of sulfur hexafluoride and other sulfurmdash;fluorine compounds. A Si29isotope effect on the fluorine chemical shift has been observed for silicon tetrafluoride.
