WebbWe have 400 MHz NMR machine. For small molecules at the same frequency sometimes we do not get the desired 13C spectra although we know from proton that it is the same … WebbThe reason why we use Hertz, is because it's the same coupling constant no matter what NMR spectrometer you're using, so it doesn't matter what the operating frequency is. You're going to get the same coupling constant. Alright, if we look at the actual NMR spectrums, over here is a zoom-in of the actual NMR spectrum.
