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 ...

Unfortunately, many 1H-NMR spectra are severely overlapped due to the multiplet structure caused by homo-nuclear scalar couplings. "Pure shift" NMR spectra, also known as broadband homonuclear ...
