The potential of heteronuclear MAS NMR spectroscopy for the characterization of (15)N chemical shift (CS) tensors in multiply labeled systems has been illustrated, in one of the first studies of this type, by a measurement of the chemical shift tensor magnitude and orientation in the molecular frame

The magnitudes and orientations of the 15 N chemical shift tensor of [1-15 N]-2-deoxyguanosine were determined from a polycrystalline sample using the two-dimensional PISEMA experiment. The magnitudes of the principal values of the 15 N chemical shift tensor of the N1 nitrogen of [1-15 N]-2-deoxygua
The results of various 15 N solid-state NMR experiments perin the molecular principal axis system (PAS) is necessary formed on solid samples of doubly 15 N-labeled 3,5-dimethylpyrafor the analysis of several solid-state NMR experiments, e.g., zole, 5-methyl-3-phenylpyrazole, (PMP), and 3,5-diphenylp
The anisotropy of the chemical shift tensor in solid fluorine has been measured by several independent methods to he (1050\*50} x 10-6. This value is slightl,v smaller than the estimated paramagcetic part of the chemical shift from the spin-rotation constant in the gaseous state.
