Please prepare your samples in the designated area or under a hood, and not on top of the magnet. The chemical shifts (d) of solvent signals observed for 1 H NMR and 13 C NMR spectra are listed in the ...
If the sample does not lock, please make sure that you followed the "NMR-basic-operation" procedure, in particular, make sure that you followed the procedure about sample preparation. Do you have ...
Most nuclear magnetic resonance (NMR) users dissolve their samples in deuterated versions of popular solvents such as chloroform, acetone, or dimethyl sulfoxide. For many purposes, such as reaction ...
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 ...
