Calculated Spin-Spin Splitting Spectra |
When you have adjacent protons the appearence of the proton NMR spectrum depends on 2 things. |
a. The difference in chemical shift, between protons A and B. b. The interaction between the protons that is called the coupling constant, J. |
In this section you can see how the appearence of the spectrum changes with chemical shift at a constant value of the coupling constant, J. |
