Glycine is an excellent setup compound for 13C CPMAS NMR measurements.  Its utility in this regard has been described in detail.1,2  It can easily be observed in one scan and has reasonably short 1H T1's, allowing it to be used for 1H 90 pulse calibration...
Seemingly simple NMR spectra often contain much more information than one might think.  For example, the 1H NMR spectrum of 1,4-dioxane is primarily a singlet from which one obtains only an isotropic 1H chemical shift value.  There is however much...
The amplitude of the 2H lock signal provides information for an electronic feedback circuit which continuously corrects the magnetic field strength (by way of a B0 shim) to compensate for environmental instability.   A poor 2H lock signal will provide...
