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 ...

Solid-State NMR has become an important method in zeolite research ... Such model studies are usually performed by the investigation of a large number of model compounds (e.g. to establish a chemical ...

Wütrich in 2002 (chemistry), and P. Lauterbur & P. Mansfield in 2003 (medicine). The utility of NMR stems from the fact that chemically distinct nuclei differ in resonance frequency in the same ...
