The "N NMR spectra of the Ginside cis-fused conformer of perhydropyrido[1,2-~][1,3]thiazine shows a shielding of the nitrogen of 23.0 ppm relative to the trans-fused conformer. In contrast, "N shifts for the cisand trans-fused conformers of perhydro-oxazolo[3,4-a]pyridine and perhydrothiazolo[3,4-a]
## Abstract The ^15^N chemical shifts of thirteen NHโpyrazoles in the solid state and of seven NHโpyrazoles in [^2^H~8~] THF solution at 170โ175 K (with frozen annular tautomerism) are reported. The solidโstate values are discussed using an additive model. The differences in chemical shifts between
