How to calculate J(C-F) value in 13 C NMR spectrum...? needs plz help me out
There are some good examples here https://ekwan.github.io/pdfs/nmr/lecture%203.pdf
What is the maximum C-F coupling constant that can be observed in 13C-nmr? 230-250 or above this also possible?
I want to develop the figure like attached figure. How can I get, peak period and significant wave height at any given location.
