A great source of satisfaction in the chemistry lab is seeing a beautiful nuclear magnetic resonance (NMR) spectrum that gives you all the information you want.   A beautiful 13C NMR spectrum means that the signal to noise ratio is large enough to see all of the resonances (visible as peaks), the peaks are tall and sharp and the baseline is flat.Have you ever had trouble producing such spectra?  It can be frustrating when your 13C NMR spectrum is missing peaks or taking a very long time. So what’s the problem?  It could be that the molecule...
