In present work set of eight Schiff bases derived from substituted salicylaldehydes and aliphatic and aromatic amines has been studied in the solid state by 15 N and 13 C CPMAS NMR methods. 15 N CPMAS NMR measurement is especially useful for investigation of the tautomerism in the compounds consider
The inรuence of hydrogen bonding (HB) on the 13C chemical shift tensors in four solid amino acids was studied by the ab initio gauge-included atomic orbital (GIAO) approach. The results of the present calculations were compared with those predicted previously and with the experimentally observed shi
## 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
