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 ...

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 ...

13C, 11B, 31P, 29Si, 195Pt, or practically any "X" nucleus with automatic probe-tuning. This new, truly state-of-the-art NMR spectrometer, operating at 300MHz for 1H observation was installed in ...
