## Abstract The X‐ray crystal structure of 1__H__‐pyrazole‐3‐(__N‐tert__‐butyl)‐carboxamide was determined. In the solid state, the ^13^C and ^15^N CP/MAS NMR spectra correspond to this tautomer. In solution, both tautomers are present in a ratio that depends on the temperature (at 293 K, 90% 3‐sub
