In 19F NMR spectroscopy, the F nuclei behave just like protons in 1H NMR spectroscopy in that they have a nuclear spin quantum number of 1/2. How many 19F NMR resonances do you expect for PF5? (Assume a static structure. In other words, the axial and equatorial do NOT rapidly scramble and change positions on the timescale of the NMR experiment.)
Depending upon on the spectrophotometer, if it can recognize axial and tlequitorial then it would happen as said above. In other case it would be a multiple(qutret of trplet or triplet of quatret.
Whatever I have explained above is 31P spectrum. F19 NMR as follows....
Both Fa and Fe couple with P separately.
Thank you and please let me know if you have any further queries.
