Carbon-13 NMR of fluorinated compounds using wide-band fluorine decoupling☆

Derick W. Ovenall; James J Chang

Abstract Fluorine-decoupled 13C NMR spectra for a number of perfluorinated organic compounds are reported and discussed. The spectra were obtained with a Bruker HFX-90 spectrometer using a modified probe and a decoupler producing up to 50 W of noise-modulated radio frequency power. Multiple decoupling of widely spaced 19F resonances is complicated by large Bloch-Siegert shifts but these can be compensated for empirically.
