摘要：

The first example of desmotropy in azoles has been found concerning 3-methyl-4-nitropyrazole and its tautomer, 5-methyl-4-nitropyrazole: the crystal and molecular stucture of both tautomers has been determined by X-ray analysis, C-13 CPMAS NMR spectroscopy has been used for studying the isomerization processes in the solid state.
