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 ...

In order to better compare NMR spectra collected at different field strength, it has become custom to convert frequency to a dimensionless quantity called chemical shift with unit ppm (parts per ...

Beginning from a chemical formula and standard NMR experiments, peaks are automatically chosen and entered into a correlation table. This data is then interpreted using a structure ... These ...
