1D 19F-NMR spectrum of 300 mM 3-chloro-2,4,5,6-tetrafluoro-benzotrifluoride in benzene-d6. Each peak is enlarged to show detailed structures (1 ppm width). Peak assignments are as follows: 1 (−118.0 ppm), 2 (−126.5 ppm), 3 (−135.5 ppm), and 4 (−160.5 ppm) are identified as F2, F4, F6, and F5, respectively. The 19F signal of the trifluoromethyl group is not observed in this frequency region.
