In problems 4.28 to 4.51, refer to Table 4.3 for isotopic abundances where needed.

The 19F NMR spectrum of the octahedral ion [PF5Me]‾ shows two signals (δ – 45.8 and –57.6 ppm). Why are two signals observed? From these signals, three coupling constants can be measured: JPF = 829 Hz, JPF = 680 Hz and JFF = 35 Hz. Explain the origins of these coupling constants.
