The feasibility of broad band fluorine decoupling for 13 C NMR spectroscopy, employing a new composite pulse sequence, is shown. The application of this sequence allows the decoupling of fluorine nuclei over almost the total range of chemical shifts in fluoroorganic compounds, at magnetic fields of up to 2.3 T, without extensive demands on the decoupler power amplifier. The range of expected chemical shifts of fluorine bonded to carbons is briefly discussed.
