Abstract

Three N‐substituted pyrazoles and three N‐substituted indazoles [1‐(4‐nitrophenyl)‐3,5‐dimethylpyrazole (1), 1‐(2,4‐dinitrophenyl)‐3,5‐dimethylpyrazole (2), 1‐tosyl‐pyrazole (3), 1‐p‐chlorobenzoylindazole (4), 1‐tosylinda‐zole (5) and 2‐(2‐hydroxy‐2‐phenylethyl)‐indazole (6)] have been studied by NMR spectroscopy in solution (^1^H, ^13^C, ^15^N) and in the solid state (^13^C, ^15^N). The chemical shifts have been compared with GIAO/DFT calculated absolute shieldings. Some discrepancies have been analyzed. Copyright © 2006 John Wiley & Sons, Ltd.
