## Abstract A ^13^C NMR study of new isoxazol‐5‐ones has been carried out in different solvents. Mathematical analysis of the tautomeric ring proton exchange in pyridine solvent indicates that the relative contributions of the NH, CH and OH tautomers are respectively 10 ± 5, 15 ± 3, 10 ± 8%, while

A detailed analysis of the I3C NMR spectra of the 1-N-and 3-N-methyl derivatives of lH-2-(2,4-dimethoxyphenyI)imidazo[4,5-~]pyridine, utilizing long-range couplings and 2D 'H-I3C correlation experiments, has led to an unambiguous assignment of all carbons. Comparison of these definitive assignments
## Abstract The tautomerism of 5(6)‐methoxy‐2‐{[(4‐methoxy‐3,5‐dimethyl‐2‐pyridinyl)methyl] sulfinyl}‐1__H__‐benzimidazole (omeprazole) was determined in solution, __K__~__T__~ = 0.59 in THF at 195 K, in favor of the 6‐methoxy tautomer. The assignment of the signals was made by comparison with its
## Abstract Geminal ^15^N^13^C coupling constants have been measured in a series of ^15^N‐enriched 1‒phenyl‒3,5‒dialkyl‐substituted pyrazoles. The importance of the orientation of the nitrogen lone‐pair in determining the magnitude of ^2^__J__(^15^N^13^C) values is reflected in the enhanced coupli
Comparison of the "C and "N NMR spectra of 8-azatheophylline with those of its three methylated derivatives and other model compounds from the literature showed that 8-azatheophylline exists to the extent of 80% in the N-2 tautomeric form in DMSO solution.
13C and 17O NMR spectra are reported for three series of Schi † bases : 2-(aminomethylene)cyclohexanones (1), salicylideneamines (2) and N-(2-hydroxy-1-naphthalenylmethylene)amines (3). The 13C and 17O NMR data show that Schi † bases 1 exist in ketoenamine form, 2 in enolimine form and 3 as an equil
