The chemical shifts (d) of solvent signals observed for 1 H NMR and 13 C NMR spectra are listed in the following table. The multiplicity is shown in parentheses as 1 for singlet, 2 for doublet, 3 for ...

It is hoped that this presentation of the basics of NMR spectroscopy is more accessible than the commonly found one in textbooks or websites. Almost all samples give a NMR spectrum This facility deals ...

A frequently documented NMR spectrum is the 1D 13 C carbon spectrum, which is less sensitive than the 1 H spectrum. Proton decoupling during the FID acquisition can boost its sensitivity (Figure 1).
