Abstract Because of experimental and theoretical interest in long-range 1 H [BOND] 19 F and 13 C [BOND] 19 F coupling constants between proximate atoms, a series of N- alkylfluoroquinolinium compounds was synthesized and the NMR parameters were accurately measured. By means of spin tickling and selective population inversion difference spectroscopy, the 5 J (HF) and 4 J (CF), which are associated with the proximate fluorine ...
