## Abstract The ^15^N chemical shifts of thirteen NH‐pyrazoles in the solid state and of seven NH‐pyrazoles in [^2^H~8~] THF solution at 170–175 K (with frozen annular tautomerism) are reported. The solid‐state values are discussed using an additive model. The differences in chemical shifts between
## Abstract Schiff base derivatives of 2‐hydroxynaphthylaldehyde were studied by means of ^13^C and ^15^N cross‐polarization magic angle spinning NMR spectroscopy and deuterium isotope effects on ^15^N chemical shifts, ΔN(D), in the solid state. ΔN(D) in the solid state provided evidenced for the p
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
## Abstract The ^13^C and ^15^N CPMAS NMR spectra of 18 pyrazoles substituted at position 1 by dinitrophenyl and trinitrophenyl (picryl) groups have been recorded. To help in the assignments, some of these compounds were studied in DMSO‐__d__~6~ solution. Phenomena such as the conformation of the _
We demonstrate a dipolar-chemical shift correlation technique for sign-sensitive determination of the torsion angle in solid peptides and proteins under magic-angle spinning. The indirect dimension of the experiment is obtained by separate but synchronous evolution of the magnetization under the 15
